Abstract
An arrayed waveguide grating includes: at least one input waveguide; an input slab waveguide connected to the input waveguide; a plurality of output waveguides; an output slab waveguide connected to the output waveguides; and an arrayed waveguide. The arrayed waveguide includes: M channel waveguides connected between the input slab waveguide and the output slab waveguide; and a phase correcting portion configured to provide a predetermined phase to at least a part of the M channel waveguides by a form of the at least the part of the M channel waveguides being changed.
