Have worked in most areas of semiconductor laser fabrication and test, including modeling, design, fabrication, process development, reliability testing, and failure analysis. Ph.D. in VCSEL reliability and failure analysis; have published many of the papers available on those subjects. Have worked for most of the US VCSEL suppliers, including HP/Agilent (now Avago), Finisar (formerly Honeywell / AOCD), Emcore, and JDSU (formerly Picolight). Primarly expertise in semiconductor laser reliability testing and failure analysis; secondary expertise in fiber optic transceiver reliability testing and in electrostatic discharge control.
