摘要：
A single core bidirectional optical device having a light emitting element that is provided on the terminal of one optical fiber and makes light incident to the optical fiber, and a light receiving element for receiving light of the optical fiber, comprises a wavelength multiplexing/demultiplexing coupler that is provided on an optical axis of light incident to and emitted from the optical fiber and includes therein wavelength separating film for separating the light to light of one side and light of another side for every wavelength; a light emitting element provided on the direction of the light of the one side which is separated by the wavelength multiplexing/demultiplexing coupler; and a light receiving element provided on the direction of the light of the other side which is separated by the wavelength multiplexing/demultiplexing coupler.
