Abstract

Low-driving-current and high-eye-margin 10-Gb/s operation was demonstrated by a GaInAsP/InP distributed reflector (DR) laser with wirelike active regions. The reduction of modulation bias currents was realized by the high modulation efficiency of five-stack quantum wirelike active regions as well as thin optical confinement layers for a shorter carrier transit time. A mask test of 10 GbE with 20% margin was passed with a low bias current of 10 mA, and the maximum 3-dB bandwidth was over 15 GHz.
