【発明の名称】量子井戸光デバイス
Document Type and Number:
Japanese Patent JP2674626
Kind Code:
B2
Abstract:
Information borne by an optical signal at first wavelength ( lambda 1) is transferred intact to another optical signal at a second and different wavelength ( lambda 2) and vice versa via an optoelectronic circuit employing quantum well devices (2,4) connected serially to facilitate self electrooptic effects therein. The optoelectronic circuit accepts two input signals (30,31)) and provides two output signals (32,33) wherein an input signal and its corresponding output signal are the same wavelength. Bidirectional information transfer equivalent to bidirectional wavelength conversion is permitted b the optoelectronic circuit.
