ABSTRACT:
An optical wavelength converter is provided that utilizes an optical interferometer configured to efficiently and rapidly shift the frequency of an optical signal and to automatically separate a pump signal from the optical signal and a frequency-shifted signal. The wavelength converter is configured with a signal port for accepting an input optical signal, of a first wavelength, to be processed for producing an output signal of a second wavelength, and a pump port for accepting a laser pump signal of a pump wavelength. An optical interferometer is connected to the signal and pump ports to separately receive the input signal from the signal port and a pump signal from the pump port and to inject each received signal independently into a nonlinear medium. In the nonlinear medium, the input and pump signals nonlinearly interact via a nonlinear optical property of the nonlinear medium to generate an output conjugate signal of a second wavelength.
