Upcoming Talks

Recent designs for novel infrared fiber amplifiers in all-optical unregenerated DWDM transmission circumnavigating the Earth with satellite free-space and subsea fiber lightwave systems are discussed. Practical architectures and timelines for deployment of these novel amplifiers and systems are presented. The talk will cover the following points: +Motivation for This Work +Bottom Line Up Front +Basic Elements of Lightwave Communications Systems +Key Spectral Operating Bands for IR Fiber Amplifiers +Design of 1550 nm Fiber Amplifiers for Satellite Free Space DWDM Transmission (Developed at Fibertek) +System Design for 1550 nm 40,000 km Satellite Free Space Unregenerated Transmission +Design of 2000 nm Fiber Amplifiers for Terrestrial/Subsea Fiber Optic DWDM Transmission (Developed at RET and Associates) +System Design for 2000 nm 40,000 km Fiber Optic DWDM Unregenerated Transmission +Comparison of Free Space Satellite and Fiber Optic Terrestrial/Subsea Fiber Amplifiers and All-Optical Unregenerated Transmission Systems that Circumnavigate the Earth +Conclusions and Summary

Dr. Robert E. Tench received a B.A. in Physics with High Honors from Swarthmore College in 1978 and a Ph.D. in Physics from MIT in 1985. The title of his dissertation was "Precision Studies of Atom-Field Interaction in Vapors" and his thesis supervisor was Prof. Shaoul Ezekiel of EECS and AeroAstro. His photonics and fiber optics career has involved research, development, and manufacturing at AT&T and Lucent Bell Labs, Agere Systems, the National Security Agency, Johns Hopkins University Applied Physics Laboratory, Cybel LLC, and Fibertek. He is currently President and Chief Scientist at RET and Associates LLC (www.retandassociatesllc.com). He has placed over two dozen photonics and fiber optics products into manufacture, has twelve patents granted or pending, and has published over 115 journal and conference papers.
