- Abstract
- Provided is a planar lightwave circuit (PLC) type optical transceiver module, in which for a diplex optical transceiver module that uses different wavelengths in upstream and downstream, an optical waveguide connected to a light-receiving unit is a multi-mode waveguide and an optical waveguide connected to the light-emitting unit is a single mode waveguide, and further, for a triplex optical transceiver module that uses one upstream wavelength and more than two different downstream wavelengths, an optical waveguide connected to the light-receiving unit, which is a waveguide-type photo diode, is a multi-mode waveguide and an optical waveguide connected to the light-emitting unit is a single mode waveguide, whereby even when there is an alignment error of a thin film filter due to irregularity provided in forming a trench, the optical waveguide connected to the light-receiving unit is formed wider than the optical waveguide connected to the light-emitting unit so that the loss during transmission of the optical signal to the light-receiving unit is minimized.
