Abstract
An optical transceiver includes a plurality of light sources having a ring resonator, a reception antenna to receive light, and a wavelength-separating filter to separate, from the light received by the reception antenna, light of a same wavelength as the light output from a part of the plurality of light sources. The wavelength-separating filter is composed of the ring resonator included in the light source.
