Abstract :
A monolithic semiconductor laser array on a p-type substrate with low threshold current and uniform characteristics, is required for parallel high-speed optical interconnections. The calculated results indicate that the threshold current should be lower than about 3.0, 1.4, and 0.7 mA at 25°C for 200 and 500 Mbit/s and 1 Gbit/s applications, respectively, to get an error-free transmission at 850 °C with a shorter turn-on delay time. This paper fully reviews the ultralow threshold properties of our 1.3 μm strained-multi-quantum-well (MQW) laser
