Broadband Chromium-Doped Fiber Amplifiers for Next-Generation Optical Communication Systems
Date and Location
Thursday, February 9, 2012 5:00 PM – Networking + Complimentary Buffet 6:00 PM – Presentation Zen Buffet 21610 Victory Blvd. Woodland Hills, CA 91367Abstract
We report the first experimental breakthrough of a net gain of optical signals in a broadband chromium-doped fiber amplifier (CDFA) for next-generation optical communication systems. Current fiber amplifiers, including commercial erbium-doped fiber amplifier, cover only a relatively small portion of the entire transmission bandwidths (1300-1600 nm) of the low-loss windows of silica fibers. The newly developed CDFAs have opened up the possibility of utilizing the 300-nm entire spectrum of the low-loss fibers to further increase the transmission capacity. In this work, we present the experimental demonstration of a net gain of 1.2 dB employing gain enhancement technique. With the help of an optical-fiber system examination for the CDFA, a 40-Gb/s error-floor free data transmission was successfully demonstrated by realizing the high-speed transmission of signal with gain through the chromium-doped fiber (CDFs). Further gain improvement in the CDFAs employing few-mode or single-mode CDFs will be presented and discussed.Speaker’s Biograpy
Dr. Cheng earned 15 years of experience as a R&D Engineer in the USA, and then was appointed a Full Professor at National Sun Yat-sen University, Kaoshiung, Taiwan, where he founded and became the Director of the Institute of Electro-Optical Engineering (1994–2000), and Dean of College Engineering (2002–2005). In 2007 he Chaired the Southern Taiwan Opto-Electronics Center of Excellence. Presently he is a Program Director of Optoelectronics in the National Science Council of Taiwan providing research grants and direction. He served as the Chair of the IEEE/LEOS Taipei Chapter 1999 and 2000, reporting a 54% member increase during his term. He was an invited speaker at LEOS Annual Meeting at 2003 and 2005. He has volunteered to organize and chair the 16th OECC (2011) (OptoElectronics and Commun. Conf.) and 11th OECC (2006), a Joint Conference of IEEE/Photonics. On scientific production, Dr. Cheng authored or co-authored 115 papers in international journals totaling 740 citations, 75 papers in international conferences and 81 papers in national conferences, and holds 17 patents including 7 granted by the US.
While Dr. Cheng was in United States, he gave seminal contributions to the development and growth of high-speed semiconductor lasers with semi-insulating (SI) blocking layers. In 1987–1993, he was the first to propose and demonstrate low-threshold, high-power, and high-speed 1.3 µm buried crescent lasers with the iron and cobalt-doped SI current blocking layers. The record lowest-threshold current of 8 mA, highest-output power of 42 mW/facet, and highest 3-dB modulation bandwidth of 22 GHz were reported for 1.3 µm lasers with p-doped active SI layers.
In Taiwan, Prof. Cheng has contributed to passive fiber-optics components and photonic packaging technology. He and his team developed flat-top 50 GHz birefringent interleaver using GTE (Gires-Tournois Etalon). He has reported an amplified spontaneous emission spectrum of CDFs with a broadband emission of 1.2 to 1.6 µm. On fiber misalignment and post-weld efficiency loss in laser module packages, Dr. Cheng and his team have made milestone contributions in a series of papers describing the guidelines of high-efficiency design, as well as the novel technology of plastic transceiver packaging using carbon nanotubes.
As an Engineer, Prof. Cheng has given contributions to the photonic packaging technology and technology transfer to industry for cost-effective and compact solid-state laser modules with good beam quality, small size, high efficiency, and long lifetime. This was a record long lifetime for green laser modules using regular size battery. Two US and one Taiwan patents were awarded. The original prototype designed by Prof. Cheng had been transferred to Quarton in 1999. Quarton then became the first solid-state laser company in Taiwan, and is currently the top-five sale for laser pointer in world since 1993 and top sales for green laser modules in Taiwan.

An Overview of SCADA in Power Systems
A Professor for a Day Series
Tuesday, January 10th, 2012 3:00 PM Jacaranda Hall 1568 California State University, Northridge 18111 Nordhoff Street Northridge, CA 91330Abstract
SCADA systems are used worldwide in a variety of automation applications especially in Power automation. The first part of the talk will elaborate the basics of SCADA systems, the use of SCADA systems in generation, transmission and distribution of electric power. Although SCADA systems are used extensively in many industries, they are proprietary items belonging to individual companies, and hence very few technical details about them are available to students and researchers. Setting up the SCADA laboratory was therefore of great importance, as it provides a research facility incorporating both hardware and software used for the adaptive and intelligent control of integrated power systems. Jamia Millia Islamia has established a SCADA laboratory and a Substation automation laboratory to cater to this need. The second part of the talk will highlight the two laboratories in detail.

Abstract
We describe a theoretical and experimental program to develop the inspection and monitoring functions using various sensors along with development and usage of needed visual sensor and MAV technology for persistent intelligence, reconnaissance, maintenance and surveillance for obscured or logistically challenging assets in non-urban environments such as US Power Grid. The system is self-monitoring. This sophisticated mechanism requires a real-time operation to sustain the quality-of-service. We discuss issues in design and information propagation in such sensor clustered topology, optimization for power-aware networking, and link and node capacity assignment to achieve the desired goals.
