Principal Engineer

§  Team leader (ONTG) on overall module design for several DWDM optical amplifiers and pump laser modules.

§   Principal designer of high power lasers drivers and optical amplifier controls including EDFA, Raman amplifiers and transient control, greatly increasing reliability while reducing costs.

§   Principal designer of heater controls for Bragg gratings, EDFAs and FBG section of FBG stabilized lasers, providing greater system stability.

§   Principal designer of wide dynamic range power monitoring photodiode TIAs, allowing common circuits for many modules and reduced factory troubleshooting.

§   Design of high speed data paths at 10Gbs and 600Mbs (mux/demux at 16:1), mostly as FEC-encoded SONET using complimentary ECL/PECL in ASIC GaAs/CMOS devices.

§   Oversaw integration of electronics, FPGA firmware, embedded software, photonics, mechanical and system level software, ensuring that the disciplines mesh cleanly.

§   RF designer on FEC based 10Gbs optical transceiver, supported group with my experience.

§   Analog and hybrid design on voice/data orderwire on service channels.

§   Analog consultant for Component Qualification group.

§   Patents on optoelectronics.
