Abstract
An optical signal processing apparatus using a planar lightwave circuit (PLC) with a waveguide-array structure includes a PLC board including a waveguide-array structure, a cylinder lens for collimating optical signals emitted and output from the PLC board into parallel beams, a condenser lens for condensing, for each channel, optical signals output by passing through the cylinder lens, and a light receiving element for receiving optical signals condensed on at least one channel from the condenser lens and converting the optical signals into electrical signals, wherein the PLC board divides an optical signal input thereto into a plurality of different optical signals and outputs the optical signals at different propagation angles.
