| An optical wavelength converter, particularly useful in a wavelength-division multiplexing communication system, including a semiconductor junction in one arm of a Mach-Zehnder interferometer through which a data signal at a first wavelength and a probe signal at a second wavelength counter propagate. The junction is reversed biased into avalanche to selectively absorb the data signal and thereby phase modulate the probe signal according to the data impressed on the data signal. The phase modulated probe signal is beat against an unmodulated probe signal, thereby converting the wavelength of the optical carrier. A tunable laser may produce a probe signal of selectable wavelength. The data signal may first be converted by cross-gain modulation to a third wavelength out of band from the other signals before it is interacts with the probe signal. | ||||||
