Abstract
We investigate a coherent feedback squeezer that uses quantum coherent feedback (measurement-free) control.
Our squeezer is simple, easy to implement, robust to the gain fluctuation, and broadband compared to the existing
squeezers because of the negative coherent feedback configuration. We conduct a feasibility study that looks at
the stability conditions for a feedback system to optimize the designs of real optical devices. The feasibility
study gives fabrication tolerance necessary for designing and realizing the actual device. Our formalism for the
stability analysis is not limited to optical systems but can be applied to the other bosonic systems.
