Abstract

A three-segment laser, when separately pumped, shows both frequency switching and continuous tuning with a modulation current applied to the middle segment. The wavelength changes are attributed to gain peak shift with the carrier concentration and carrier-induced index change. A total wavelength change of 61 Å, a continuous tuning range of 4.1 Å, and a tuning rate of -0.74 Å/mA are obtained. The laser may be useful in optical FM fiber communication. [ABSTRACT FROM AUTHOR]

Abstract

Techniques for passivating In0.53Ga0.47As, InGaAsP, InP, and InGaAsP/InP p-n junction structures with polyimide have been developed. Low stable leakage current is maintained for prolonged bias, even after exposure to high temperatures (∼320 °C) during packaging. 150-μm-diam In0.53Ga0.47As photodiodes with a breakdown voltage of ∼50 V were passivated with polyimide and were found to consistently have leakage currents of ∼10 nA at a 20-V bias.Details of the passivation process are given.
