ABSTRACT:
To provide an optical device and method for manufacturing the same that allow a reduction in size and the easy fabrication of an optical splitter or an optical coupler with which the branching ratio or the coupling ratio can be dynamically changed after device production. An optical device is provided with a photonic crystal having a periodic refractive index distribution due to a periodic arrangement of a plurality of materials of different refractive indices, an input-side optical waveguide for making light incident on the photonic crystal, and an output-side optical waveguide for emitting light from the photonic crystal, and further includes an external drive portion for changing a relative position of the photonic crystal and at least one of the input-side optical waveguide and the output-side optical waveguide, thereby allowing a small, high-performance optical device to be achieved.
