NORTEL, Richardson, TX 2000 - 2005
Advanced Technology Group - Project Manager - Advanced Optical Technologies
- Developed 10 Gb/s high density, low power, low cost optical transceiver technology demonstrator.
- Prototyped 10Gb/s optical transceiver resulting in a density increase of almost 10X over the industry standard Small Footprint 10 Gigabit Transponder MSA TOMCAT module.
- Demonstrated high performance direct connection 10 Gb/s electrical interface showing significantly better signal integrity than traditional approaches and eliminating expensive MUX/DEMUX circuitry.
- Coordinated fabrication of prototype devices across six sites in the United States, Canada, and the United Kingdom.
- Analyzed optical backplane technologies as a replacement for copper interconnects in high performance, high density systems.
- Analyzed system requirements, impacts, costs and adoption strategies for optical backplane technologies and contrasted with advanced copper interconnect technologies. Evaluations included impacts on design, cost, thermal design, reliability and system complexity.
- Created a multi-company consortium to compete for a 2004 NIST Advanced Technology Program grant. Led the team, consisting of five companies and two universities, through development of a $13 million optical backplane research and development program. The proposal successfully passed the NIST technology evaluation gate. Though it was not one of the proposals funded, the evaluators strongly suggested the consortium resubmit for the 2005 competition.
- Served on the University of Texas at Dallas Telecommunications Engineering degree program Industrial Advisory Committee (2003-2005). This committee makes recommendations and provides guidance for the development and continued accreditation of the degree plan.
- Analyzed new optical networking component technologies for technical feasibility and applicability in future networks. Technologies developed at start-up companies, universities and Nortel were evaluated. This resulted in programs for advanced development being established for the most promising technologies. For example, a photonic bandgap material (photonic crystal) based optical limiter from the University of Toronto has lead to a multiyear research engagement for which I have been the technical prime.
- Evaluated Quantum Key Distribution (Quantum Cryptography) technology and developed the product strategy.
- Developed network concepts for wavelength division multiplexing (WDM) metro access networks driven by advances in component technologies and developed advanced component concepts based on future network architectures.

Stanford University, Stanford CA 1987-1993
Ph.D. Thesis Research Summary
- Investigated the fast time scale rotational and librational motions of ordered liquids such as liquid crystals and their analogs. Liquid crystals have a high degree of local order that persists for an extended time period, providing an opportunity to investigate the effect of local liquid structure on the dynamics of molecules. A clear understanding of the structureand dynamics of liquids is required for the optimization of chemical reactions, materials processing and the development of materials. Developed and refined a unique 200-300 femtosecond tunable pulsed laser system. This laser system has the capability to measure these material dynamics on a scale from femtoseconds to tens of nanoseconds; an improvement of four orders of magnitude over most prior experiments.
