Patent ID: 7039285

Claim:
A method of manufacturing a photonic crystal comprising the steps of: a first step of providing a predetermined film for which a plurality of photonic crystals, each having a different cyclic structure is manufactured; and a second step of irradiating predetermined particles or electromagnetic waves onto a mask having a plurality of regions, each region having passage sections arrayed based on a cyclic structure predetermined for each region, and a mask substrate to hold said passage sections, wherein said mask is constructed so that (a) when said particles are irradiated in said second step, said particles substantially pass through only said passage sections or (b) when said electromagnetic waves are irradiated in said second step, an energy density difference is produced on said film due to a diffraction effect based on said cyclic structure, the direction of said array corresponds to the direction of a fundamental grating vector of said photonic crystal, said plurality of regions are arranged to each correspond to a different one of the cyclic structures of said photonic crystals, and the direction corresponding to the direction of at least one said fundamental grating vector in said each region is consistent throughout all said regions.
