摘要

An intrinsically stable type I optical parametric oscillator was built with a periodically poled KTiOP0₄ Crystal to generate a stable, bright, cw, broadband phase-squeezed beam. A 3.2 dB sensitivity enhancement of optical interferometry was demonstrated on weak electro-optic modulation signals within a 20 MHz squeezing bandwidth. This also realized a channel capacity increase beyond that of coherent optical communication.
