Frequency Pulling and the Linewidth Enhancement Factor in Optically Injected Semiconductor Laser

Abstract

The effect of the linewidth enhancement factor (LEF) on the frequency pulling behavior in optically injected lasers is theoretically investigated. The frequency pulling is found to be exponentially dependent on the LEF. This dependence is systematically revealed and explained.
