摘要: We describe a polarimetric coherence multiplexed system that uses source with short length to reduce the effect of cross talk and phase-induced intensity noise. The is constructed sections highbirefringence optical fibers, which allow differential path lengths be matched within micrometer accuracy. A minimum detectable phase sensitivity 3 microrad/ radicalHz has been demonstrated.
