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