Abstract :
Summary form only given. In conclusion, we have demonstrated low-bias, high-temperature modulation of tapered thickness waveguide BH InP MQW lasers with an external optical feedback. A penalty-free transmission over 40 km was confirmed with -14-dB feedback at 85 C. We confirmed that our lasers have a potential for low cost subscriber systems.
