摘要： To provide an optical bidirectional communication module which does notrequire complicated optical axis alignment and is advantageous for

miniaturization.SOLUTION: One input / output port 20, a multiplexing / demultiplexingunit 30, n transmitting units 40-1 to 40-n, m receiving units 50-1 to 50-m An input / outputwaveguide section 60 for connecting between the input / output port and themultiplexing / demultiplexing section, a transmission side waveguide section 70connecting between the multiplexing / demultiplexing section and the transmissionsection, and a section between the multiplexing / demultiplexing section and thereceiving section A receiving side waveguide section 80 to be connected, a multiplexingsection 73 formed as a part of a transmission side waveguide section in the middle of thetransmission side waveguide section, and a receiving side waveguide section And a firstbranching section 84 formed as a part of the section. The input / output port, themultiplexing / demultiplexing unit, the input / output waveguide unit, the transmissionside waveguide unit, the reception side waveguide unit, the multiplexing unit and the firstdemultiplexing unit are constituted by silicon waveguides.BACKGROUND OF THEINVENTION
