Abstract:
An arrayed waveguide grating optical multiplexer/demultiplexer comprising:at least one first optical waveguide; a first slab waveguide including first and second portions which are divided along an intersecting face intersecting an optical path in the first slab waveguide; an arrayed waveguide connected to said at least one first optical waveguide via said first slab waveguide; a second slab waveguide; a plurality of second optical waveguides connected to said arrayed waveguide via said second slab waveguide; and a slider fixed at a temperature shifted from a predetermined temperature to compensate a center wavelength difference between a target center wavelength of optical transmission of the arrayed waveguide grating optical multiplexer/demultiplexer at the predetermined temperature and the measured center wavelength of optical transmission of the arrayed waveguide grating optical multiplexer/demultiplexer at the predetermined temperature before the first slab waveguide is divided to the first and second portions, the slider being configured to cause a relative motion between the first and second portions of the first slab waveguide along the intersecting face according to a temperature change.
