Expanding amplitude-squeezing bandwidth with off-peak dispersive optical feedback.
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.
