Abstract
STM 16 (2.488 Gbit/s) system operation over a wide DFB chip temperature range of more than 120 K (from –25°C to +95°C) is presented with dispersion penalty below 1 dB after transmission across 100 km standard fibre. DFB operation at 1.55 µm with a high sidemode suppression ratio of 40 dB is achieved within –40°C to +95°C. The lasers were realised using a BRS lateral structure and a quaternary InGaAsP MQW stack with six compressively strained quantum wells and a highly detuned DFB grating.Keywords
