Low-power consumption and high-eye-margin 10 Gbit/s operation of distributed reflector laser with wirelike active regions

By introducing 5-quantum-well wirelike active regions with thin optical confinement layers, low-power and high-speed operation of GaInAsP/InP distributed reflector (DR) laser with wirelike active regions was realized. A mask test of 10 GbE with a 20% margin was passed with a low bias current of 10 mA and the 3 dB bandwidth of 15 GHz was obtained with the bias current of 28 mA.
