ABSTRACT:
In an in-plane heterostructure photonic crystal in which vacancies32are periodically arranged in each of forbidden band zones301, 302,with different cycle distances, a waveguide33is formed passing through all the forbidden band zones and point-like defects341, 342, . . .are formed in each of the forbidden band zones. Since, of all light propagating through the waveguide from the light introduction/take-out section36and having the frequency52demultiplexed from the predetermined point-like defect, the wavelength of light passing through the predetermined point-like defect is not included in transmission bands51of the waveguide in the adjacent forbidden band zone, so that the light is reflected on the boundaries351and352between forbidden band zones and introduced into the point-like defect. Thereby, the demultiplexing efficiency of light is improved. The same applies to the multiplexing efficiency.
