Optical Gyroscope with Coherent-Boosted Two-Mode Squeezed Beams

Not Accessible

Your library or personal account may give you access

Abstract

We propose a new gyroscope scheme with a two-mode squeezed coherent light as the source. With the intensity-difference measurement, the phase sensitivity is better than the shot-noise limit, and can saturate the Crámer-Rao Bound. The loss inside the gyroscope can be compensated by adjusting the squeezing parameters.
