Abstract

A pulse-excited Sagnac fiber interferometer can perform squeezing. If this squeezed radiation is injected into a second Sagnac interferometer that is functioning as a fiber gyro that is itself nonlinear, additional unfavorable squeezing occurs in the gyro. By proper phase adjustment of the injected squeezed radiation it is possible to minimize this effect as long as the Sagnac interferometer that is performing the squeezing has a sufficiently large nonlinearity.
