HIGH-SPEED MODULATION WITH LOW-THRESHOLD 1.3-MU-M-WAVELENGTH MQW LASER-DIODES

Laser diodes for optical interconnections are ideally high speed, work over a wide temperature range, and are simple to bias. This paper reports high bit-rate modulation with nearly zero bias with very low threshold 1.3 mum-wavelength laser diodes over a wide temperature range. At the high temperature of 80-degrees-C, lasing delay was 165 ps with nearly zero bias. We demonstrated 2.5 Gbit/s modulation over a wide temperature range. Eye opening was over 34% of one time slot.
