Japanese Patent JP2919329
Kind Code:
B2
Abstract:
Disclosed is an optical transmitter-receiver module, in which an optical waveguide with an optical dividing function is formed from a first end to a second end of a waveguide substrate, and the non-branched side of the optical waveguide is optically connected to an optical fiber at the first end of the waveguide substrate, and two optical waveguides on the branched side of the optical waveguide are optically connected to an optical transmitter and an optical receiver, respectively, characterized by that a first optical waveguide of the two optical waveguides is optically connected to the optical receiver at the second end of the waveguide substrate, and a second optical waveguide of the two optical waveguides comprises a turning optical waveguide which is turned back from the second end to the first end of the waveguide substrate, and the turning optical waveguide is optically connected to the optical transmitter at the first end of the waveguide substrate.
