Abstract
An arrayed waveguide grating multiplexer/demultiplexer includes an array of optical waveguides ordered in sequence from a shortest waveguide up to a longest waveguide, and identical phase shifters configured to be controlled by a same control signal. Each phase shifter increases/decreases an optical path of an optical waveguide by the same quantity based on the control signal.
