ABSTRACT:
The optical element includes photonic crystals respectively having different optical characteristics. These photonic crystals are formed in a plurality of regions on a single substrate. The optical element has a structure in which two or more kinds of media are nearly periodically deposited on one-dimensionally periodical grooves. Further, the grooves are different in direction according to locations on the deposited surface. A variety of optical elements each having different dependencies on polarization according to locations can be obtained. That is, portions or zones different in optical characteristics can be integrated on a single substrate.
