Abstract

Disclosed is an optical transmitter/receiver which is provided with: a first photodiode (16) which receives receiving light outputted from an optical fiber (20); a second photodiode (17) which has a light receiving surface (42b) that forms the same plane as the light receiving surface (42a) of the first photodiode (16); a laser diode (14) which outputs, toward the first photodiode (16) and the second photodiode (17), transmitting light inputted to the optical fiber (20); and a thin film (18), which is provided on the light receiving surface (42a) of the first photodiode (16), reflects, toward the optical fiber (20), some of the transmitting light outputted from the laser diode (14), and which passes through the receiving light outputted from the optical fiber (20). The second photodiode (17) receives some of other transmitting light outputted from the laser diode (14).
