Claim 6:
7. The method for adjusting a transmission wavelength of signal light transmitted through an optical waveguide device according to claim 1, wherein the resin includes a first resin and a second resin disposed at two positions in the optical waveguide device, and further comprising:
a step of changing, firstly, a refractive index of the first resin by irradiating the first resin with the blue light, and
a step of changing, subsequently, a refractive index of the second resin by irradiating the second resin with the blue light,
wherein a power of the blue light irradiating the second resin is lower than a power of the blue light irradiating the first resin.
