A planar lightwave circuit (PLC) of a PLC module is provided with many waveguides including a plurality of input (output) optical waveguide on a substrate. Junction faces between these input (output) optical waveguide and input (output) optical fibers are slant against the optical axis thereof. The PLC module has photodetectors opposed to corresponding junction faces disposed at the input-optical-fiber's-side (output-optical-waveguide's-side).
