Abstract
Fine particles ( ) are oriented and dispersed in a polymer medium to obtain a composite material ( ), which is high-density compression molded to such a size that a photonic band gap develops, thereby obtaining a photonic crystal element ( ). The orientation of the fine particles ( ) in the polymer medium can be carried out on a scale (tens of micrometers to several millimeters) where required manipulations can be done with ease.
