Abstract
Information borne by an optical signal at a first wavelength is transferred intact to another optical signal at a second wavelength and vice versa via an optoelectronic circuit employing quantum well devices connected serially to facilitate self electrooptic effects therein. The optoelectronic circuit accepts two input signals and provides two output signals wherein an input signal and its corresponding output signal are at the same wavelength. Bidirectional information transfer with bidirectional wavelength conversion is permitted by the optoelectronic circuit.
