Abstract
The present disclosure provides a coherent light receiving optical device. It includes: an optical switch group, each optical switch thereof is configured to switch between two different preset bands and output two signal lights or two oscillation lights corresponding to the two different preset bands; a 1×2 power beam splitter group, each 1×2 power beam splitter thereof is configured to split one of the two oscillation lights into two split oscillation lights; an optical hybrid group, each optical hybrid thereof is configured to mix the one split oscillation light from an oscillation path with one signal light from a signal path in the same preset band, to output a mixed light; a detector group, each detector thereof is configured to convert the mixed lights of two different preset bands in the mixed lights into photocurrent in the same detector, so as to multiplex the detector.
