Abstract

Switching times for polarization switching lasers are analyzed using two-mode rate equations including carrier dynamics. Two-mode operations are considered in weak, neutral, and strong coupling with a net gain difference between two modes and light output as parameters. It is found that a modulation speed is enhanced with increases in a net gain difference and a light output, and with a decrease in coupling constant. For example, when a net gainratio alpha(2)/alpha(1) is 0.2 and the light output is 20 mW, a modulationspeed of 24.3 Gbit/s for nonreturn-to-zero signals is expected.
