ABSTRACT:
An transmitter-receiver for optical communication which effectively prevents a received optical signal from being branched to a light emitting element side is disclosed. The transmitter-receiver for optical communication includes a transmission optical signal generation section, an optical signal reception section for receiving an optical signal by way of a communication optical fiber, and an optical signal branching and combining member for branching or combining an optical signal to be transmitted from the transmission optical signal generation section to the optical signal reception section. The optical signal branching and combining member is formed as an asymmetrically Y-shaped optical branching path member having a single waveguide mode. Also a bidirectional optical amplifier in which such optical signal branching and combining member is incorporated is disclosed.
