Abstract

Weak dispersive optical feedback has been proved both theoretically and experimentally to be able to reduce the intensity noise of semiconductor lasers and allow the generation of amplitude-squeezed states. I propose a novel scheme exploiting the off-peak optical feedback condition that expands the squeezing bandwidth and significantly enhances the repeatability over the most commonly utilized on-peak optical feedback scheme. Using a realistic model, I show that under the zero-frequency-pulling condition the off-peak scheme greatly enhances the squeezing bandwidth.
