ABSTRACT:
To provide an optical device whereby the optical characteristics of a lightwave circuit element can be varied with low power consumption. There is provided an optical device comprising a lightwave circuit element having one or plurality of optical waveguides, and also having a refractive index adjusting portion composed of resin located in the one or plurality of optical waveguides and/or in a portion of the area in the one or plurality of optical waveguides. The lightwave circuit element comprises an adjustment-light waveguide for guiding adjustment light that varies the refractive index of the resin, and directing the adjustment light to the adjusting portion.
