SINGLE-CORE OPTICAL TRANSCEIVER

摘要

A single-core optical transceiver 1 is an optical transceiver for transmitting or receiving an optical signal through a single optical fiber 2. The single-core optical transceiver 1 has a light emitting device 13 for transmitting the optical signal and a light receiving device 12 for receiving the optical signal. The light emitting device 13 is an LED configured including a sapphire substrate 13b arranged on a light receiving surface 12a of the light receiving device 12 so as to be coaxial with the light receiving surface 12a, and a nitride semiconductor layer 13a laid on the sapphire substrate 13b. Even with the light emitting device 13 being arranged on the light receiving surface 12a of the light receiving device 12, the optical signal from the optical fiber 2 can be received on the entire area of the light receiving surface 12a, so as to adequately improve the light sensitivity.
