Title:
Optical up / down conversion type optical phase conjugate pair signal transmission / reception circuit
Document Type and Number:
Japanese Patent JP6353342
Kind Code:
B2
Abstract:
[Problem] To provide a method capable of easily compensating waveform distortion due to a non-linear effect caused by a complicated electric circuit, and a device for implementing the method. [Solution] Provided are a method capable of effectively compensating signal degradation such as waveform distortion due to a nonlinear effect caused by an optical fiber that is an optical transfer path using an optical phase conjugate signal pair at the time of optical up-conversion or down-conversion, and a device capable of implementing the method. This emission device 25 includes an optical modulator 11, a signal source 13, an optical fiber 15, a multiplexing unit 17, a multiplexing local signal source 19, an optical detector 21, and a transmission antenna 23.
