Uncooled, low-driving-current 25.8 Gbit/s direct modulation using 1.3 ;C;m AlGaInAs MQW distributed-reflector lasers

摘要

Uncooled, low-driving-current 25.8 Gbit/s direct modulation with clear eye-opening up to 85°C is demonstrated using 1.3 μm AIGalnAs mul- tiple quantum well (MQW) distributed-reflector lasers. The peak driving currents were as low as 30.0 and 38.9 mA at 25 and 85°C, respectively.
