Abstract:
A method of manufacturing an arrayed waveguide grating optical multiplexer/demultiplexer, comprising the steps of:preparing an arrayed waveguide grating having a waveguide forming region for forming a waveguide structure and at least one slab waveguide; setting dividing lines for determining dividing planes that intersect a route of light traveling along said at least one slab waveguide, said dividing planes dividing said at least one slab waveguide into first and second divided slab waveguide portions, and also dividing said waveguide forming region into a first waveguide forming region that includes the first divided slab waveguide portion and a second waveguide forming region that includes the second divided slab waveguide; fixing a position shifting member to have a first end secured on said first waveguide forming region and to have a second end secured on said second waveguide forming region; and dividing said waveguide forming region into said first waveguide forming region and said second waveguide forming region along said dividing lines.
