Disclosed in a method and a device in which a wave number of light in the waveguide mode of a photonic crystal optical waveguide is matched with that of the incident light, or a intensity ratio of electric field to magnetic field of the light in the waveguide mode of the photonic crystal optical waveguide is matched with that of the incident light, and furthermore, in addition to the method above, the distribution of light intensity on the incident end surface in the waveguide mode of the photonic crystal optical waveguide is matched with that of the incident light. A photonic crystal optical waveguide and channel optical waveguide are joined together, and the structure of the channel optical waveguide is wedge shaped in the joint section.
A method for controlling incidence of light into a photonic crystal optical waveguide, wherein incident light travels into an optical waveguide from an outside thereof, said optical waveguide being capable of guiding the light and formed in an photonic crystal including two or more types of materials having different indexes of refraction arranged periodically in any one of one dimension, two dimensions and three dimensions, said method comprising:
