Abstract

It is shown that, similar to resonant enhancement of linear phase, birefringent phase, and chirality/optical activity by a ring resonator (RR), Berry's phase, or the geometrical phase, can be amplified by repeatedly passing light through a Berry's phase-generating element placed in a RR. Small-signal amplification of Berry's phase is equal to the resonator finesse F. This amplification can be exploited when Berry's phase is used for performing quantum computation or in fiber-optic and other sensors.
