ABSTRACT:
A photonic crystal structural body has a structure that a second mediums whose refractive index changes with an external field is periodically distributed in a first medium whose refractive index changes with the external field. An external field generator applies the external field to the photonic crystal structural body. It is possible to increase a change amount of a photonic band gap.
