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 1.3µm-wavelength laser diodes over a wide temperature range. At the high temperature of 80, 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.
