Electron-Beam Fabricated Diffractive Optics for Earth and Space Applications

Dr. Daniel Wilson
Jet Propulsion Laboratory

Thursday, October 19, 2017
5:30–7:30 PM

Moore Laboratory of Engineering, Room B270
California Institute of Technology
Pasadena, California

About the Talk: Electron-beam fabricated diffractive optical elements have proven to be enabling for a variety of NASA instruments. By combining the precision of the electronbeam tool with carefully calibrated fabrication techniques, three-dimensional surfaces can be created with accuracies down to tens of nanometers. This allows us to fabricate high-performance diffractive optics such as precisely blazed gratings and computer-generated holograms that are designed using optical wavefront engineering algorithms. Further, we have developed techniques for e-beam writing on curved surfaces, allowing us to fabricate convex or concave gratings for compact imaging spectrometers, many of which have flown on airborne and spaceborne missions (e.g. Compact Reconnaissance Imaging Spectrometer for Mars, Moon Mineralogy Mapper, and Portable Remote Imaging Spectrometer). We have also developed techniques for e-beam fabricating grayscale phase-profiled occulting spots for exoplanet imaging coronagraphs, and spot array generators for the Mars 2020 rover. This presentation will give an overview of our diffractive optics fabrication techniques and the instrument applications.

About the Speaker: Dr. Daniel Wilson is a Principal Engineer in the JPL’s Instrument Electronics and Sensors Section. He leads JPL’s efforts in developing high-performance imaging spectrometer gratings and has research interests in the design and electron-beam fabrication of diffractive optical elements and instruments. He joined JPL in 1994 and has a PhD in Electrical Engineering from Georgia Institute of Technology. He was awarded JPL’s Lew Allen Award for Excellence and the NASA Exceptional Technology Achievement Medal for his work on e-beam fabricated gratings.

How to map the Earth, or what was the Shuttle for anyway?

The IEEE Los Angeles Geoscience and Remote Sensing Society Chapter Present a Special Lecture Event!

How to map the Earth, or what was the Shuttle for anyway?

Dr. Michael Kobrick
Jet Propulsion Laboratory

Wednesday, September 6, 2017
5:30–7:30 PM

Arms Laboratory, Sharp Lecture Hall
California Institute of Technology
Pasadena, California

About the Talk: Remember when the world was flat? Not any more.  In February, 2000 NASA sent six astronauts aboard the Space Shuttle Endeavour on an 11-day mission to gather data for the first complete three-dimensional global elevation map of Earth.

The 12 terabytes of raw radar data they collected has been processed into a near-global digital elevation model with 30 meter sampling and vertical accuracy exceeding all the usual standards. The elevation information is easily the most popular and frequently downloaded data set at the land processes distribution archive, and after combining with data from other missions will form the soon to be released NASADem, a single-stop-shopping source for the best (and free!) global digital elevation data available.

Mike will describe what the Space Shuttle was originally intended for, how it evolved, and how a single good idea can turn into a mission that NASA Headquarters has called the single most important accomplishment of the Space Shuttle program.

About the Speaker: Dr. Michael Kobrick is the Project Scientist for the Shuttle Radar Topography Mission at Caltech’s Jet Propulsion Laboratory. He holds degrees from several well-meaning institutions of higher learning, including a doctorate from UCLA in Planetary and Space Physics, and for 44 years at JPL has specialized in radar remote sensing of the Earth and planets.

Before conceiving the SRTM mission he was a Principal Investigator on numerous spaceborne radar experiments dating back to the Apollo program. He served as Science Manager for the Magellan mission to map Venus with radar, and has several thousand exciting flight hours on NASA’S DC-8 research aircraft using JPL’s airborne imaging radar system. His current research interests center on the derivation of digital topographic data from interferometric radar sensors and their geoscientific applications.

Directions and Parking: Parking on the Caltech campus is accessible from Michigan Avenue, south of Del Mar Avenue. Parking is free after 5 pm. Arms Lab location: http://www.caltech.edu/map/charles-arms-laboratory-of-the-geological-sciences

Infrared Sources and Detectors for Deep-Space Science

The IEEE Los Angeles Photonics and Geoscience and Remote Sensing Society Chapters in Los Angeles Present a Special Lecture Event!

Infrared Sources and Detectors for Deep-Space Science

Dr. Ryan M. Briggs
Jet Propulsion Laboratory

Thursday, August 3, 2017
5:30–7:30 PM

Moore Laboratory of Engineering, Room B270
California Institute of Technology
Pasadena, California

About the Talk: This presentation will describe recent progress in two technology areas relevant to space science: mid-infrared lasers for molecular spectroscopy and superconducting single-photon detectors for optical communication. We have designed and fabricated distributed-feedback quantum cascade lasers for targeted detection of compounds in planetary atmospheres using in situ infrared laser absorption spectroscopy techniques. The lasers are designed for use in low-power instruments; therefore, emphasis is placed on minimizing laser operating current and reducing thermal dissipation to ~1 W. Device performance will be discussed for lasers emitting in the 4 to 10 μm wavelength range.

In order to increase communication bandwidth beyond the limits of existing radio-frequency links, NASA continues to support the development of optical communication transceivers for testing on the next generation of planetary science missions. To resolve signals transmitted from spacecraft several astronomical units away from Earth, we have developed superconducting nanowire single-photon detectors for a ground receiver at 1550 nm wavelength. The principle of operation and fabrication techniques for the detectors will be presented, and performance will be discussed for multi-pixel detector arrays developed for the first deep-space optical communication demonstrations.

About the Speaker: Ryan Briggs received his Bachelor of Science in Engineering Physics from Colorado School of Mines and his PhD in Materials Science from the California Institute of Technology. He joined the Microdevices Laboratory at JPL in 2011. Dr. Briggs has expertise in design and fabrication of integrated photonic devices, antimonide-based interband lasers, quantum cascade lasers, and optoelectronic device packaging. He is currently Principal Investigator for “Low-Power Long- Wavelength Infrared Sources for Tunable Laser Spectrometers on New Frontiers and Discovery Missions,” under the NASA Planetary Instrument Concepts for the Advancement of Solar System Observations Program.

2017 GRSS Summer School + Young Professional Event

Join us for the 2017 GRSS Summer School + Young Professional event from July 19- 21, 2017 in Arlington, Texas!  The young professional event is organized by MLA GRSS Chapter!

An elevator pitch can be one of the simplest yet most powerful tools for a researcher to network effectively with other researchers or to get your message heard by management. An elevator pitch should be short, clear, conversational, and intelligible to both non-researchers and researchers not in your niche area. It should: define who you are, describe what your research does, identify your target customers, and explain what’s unique about your research. But simply being able to craft “short” messages is not enough, it should be catered to the person you are pitching the idea to and allow them to understand and appreciate the impact and value of our research. More importantly, it’s not a sales pitch, rather an opportunity to make a good impression that will lead to a deeper dialogue about what you and your research can offer.

At this year’s GRSS Summer School (Wed-Fri, July 19-21) come and learn more about remote sensing theory and practical applications by learning from world-renowned leaders in the field. At the Young Professionals event (Fri afternoon, July 21), hone your elevator pitch skills in small teams while networking with other students, young professionals, and summer school lecturers. Each team will make their best pitch during the Networking Dinner on Friday evening in front of their fellow participants and select members of the IEEE GRSS Administrative Committee. A prize (and honor & glory) awaits the best pitch!

UV Detectors and Imaging Arrays

Dr. Micheal Hoenk
Jet Propulsion Laboratory

Wednesday, May 10, 2017
5:30–7:30 PM

2475 E Huntington Dr
San Marino, California

About the Talk: Surface passivation has been a challenge for silicon devices from the beginning, having played a critical role in the development of field-effect transistors and VLSI circuits. Early efforts to develop back-illuminated silicon detectors for ultraviolet astronomy were fraught with surface passivation problems. After discovering a critical problem with detectors in Hubble Space Telescope’s Wide-Field Planetary Camera, researchers at the Jet Propulsion Laboratory (JPL) pioneered several approaches to the passivation of silicon detectors, including the use of molecular beam epitaxy to grow a surface passivation layer on back-illuminated CCDs. Uniquely among all methods previously explored, delta-doped CCDs achieved nearly 100% internal quantum efficiency and exceptional stability. Several challenges remained in development of these detectors for spaceflight. With the recent development of wafer-scale bonding and thinning technologies, and following JPL’s acquisition and development of 200mm silicon molecular beam epitaxy equipment and processes, these challenges have now been solved. We are currently fabricating delta-doped and superlattice-doped CCDs and CMOS imaging detectors at full wafer scale, and we are exploring a variety of different silicon detectors, including technologies for imaging x-rays on nanosecond timescales, scintillation detectors for detecting gamma rays with sub-nanosecond resolution, and single photon counting detectors for astronomy and astrophysics.

About the Speaker: Dr. Michael Hoenk is a Principal Member of the Technical Staff in JPL’s Flight Instrument Detectors & Systems Group. Dr. Hoenk co-invented, developed and demonstrated the first delta-doped CCD, which provided stable surface passivation and nearly 100% internal quantum efficiency. His recent invention and development of superlattice-doped imaging detectors solved an important problem in radiation-induced surface degradation in deep ultraviolet semiconductor metrology systems. He is currently the Lead and Product Development Manager for the OCO-3 Context Cameras, and serves as Focal Planes and Detectors Chair for Team X Instruments studies. Dr. Hoenk is a recipient of several prestigious awards, including JPL’s Lew Allen Award of Excellence and NASA’s Exceptional Achievement Award.

Directions and Parking: One block west of San Marino High School on the north side of Huntington Drive. Masters Realty Meeting Room. Free street parking.

About the Talk: The CubeSat Infrared Atmospheric Sounder (CIRAS) will measure upwelling infrared radiation of the Earth in the MWIR region of the spectrum from space on a CubeSat. The observed radiances can be assimilated into weather forecast models and be used to retrieve lower tropospheric temperature and water vapor for climate studies. Multiple units can be flown to improve temporal coverage or in formation to provide new data products including 3D motion vector winds. The spacecraft will be a commercially available CubeSat and the integrated system will be a complete 6U CubeSat capable of measuring temperature and water vapor profiles with good lower tropospheric sensitivity. The CIRAS is the first step towards the development of science instruments requiring infrared measurements while reducing the cost of the payload, spacecraft and launch. Examples of science results and imagery obtained from NASA satellites as they relate to weather forecasting, and research in climate and atmospheric composition will be presented.

About the Speaker: Mr. Pagano is the Principal Investigator for CIRAS and the Project Manager for AIRS/AMSU/HSB Suite of instruments on the EOS Aqua Spacecraft. He was the lead engineer responsible for the calibration of the AIRS instrument in orbit. Prior to joining JPL in 1997, he was the Chief Systems Engineer on the MODIS instrument development program at Raytheon SBRS since 1985. He has a BS in Physics from UC Santa Barbara, and an MS in Physics from Montana State University. He holds 2 US patents and is author of numerous papers on space remote sensing systems.
