Abstract
An optical device having a waveguide that is formed in a photonic crystal and is provided with a special function utilizing a property specific to the photonic crystal is obtained. The waveguide device includes a waveguide formed in the photonic crystal having a periodic structure formed of at least two kinds of optical mediums. The waveguide is configured not to satisfy arrangement of the periodic structure so as to pass the light of a frequency in a photonic band gap range of the photonic crystal. At a prescribed portion of the waveguide, an optical non-linear medium having linear response as well as quadratic or higher-order non-linear response to the incoming energy of the photoelectric field is provided.
