| 英文摘要 | The object is to reduce the size and losses of light transmitting/receiving modules. An optical transmitting/receiving module according to the invention comprises a light emitting element for sending out an optical signal of lambda 1 in wavelength, a first optical waveguide into which this transmit optical signal is entered, and a second optical waveguide for sending out the transmit optical signal and receiving an optical signal of lambda 2 in wavelength. Characteristically, it has a directional coupling section formed by arranging the first and second optical waveguides close to each other to be half as long as the full coupling length for a light having the wavelength of lambda 1, and at the end of the directional coupling section are arranged a filter for reflecting the transmit optical signal of lambda 1 in wavelength and transmitting the receive optical signal of lambda 2 in wavelength, and a light receiving element, arranged on the opposite side to the optical waveguide substrate via the filter, for receiving the receive optical signal. |
