Abstract
An optical transmission and reception device comprises an optical transmission region including an active layer which oscillates and outputs laser beam of a wavelength .lambda.1 on a transmission state, and guides received light of a wavelength .lambda.2 different from the wavelength .lambda.1 on a reception state and an optical reception region including a light detecting device for detecting the received light guided by the active layer and converting the received light into electric signals. The optical transmission and reception device having an optimum structure for the transmission and reception can be realized. Accordingly an optical transmission and reception device having good characteristics, which are suitably used in bidirectional communications by optical subscribers' systems, and optical parallel link data transmission in computers.
