Abstract
Fine particles (23) are oriented and dispersed in a polymer medium to obtain a composite material (24), which is high-density compression molded to such a size that a photonic band gap develops, thereby obtaining a photonic crystal element (26). The orientation of the fine particles (23) 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.

A photonic crystal element manufacturing method comprising the steps of:
- (a) orienting and dispersing fine particles in a polymer medium to obtain a composite material;
- and
- (b) performing high-density compression molding of said composite material to compress it to such a size that a photonic band gap emerges, thereby obtaining a photonic crystal element.
An apparatus for manufacturing a photonic crystal element from a composite material with magnetic fine particles oriented and dispersed in a polymer medium, said apparatus comprising:
- means for applying an isostatic pressure to said composite material to compress said composite material to such a size that a photonic band gap emerges;
- means for heating said polymer medium to obtain said composite material;
- and
- means for applying an electromagnetic field to said composite material to orient said magnetic fine particles.
A photonic crystal element manufacturing method comprising the steps of:
- (a) orienting and dispersing fine particles in a liquid polymer contained in a container;
- (b) obtaining from the liquid polymer a solid composite material in which the fine particles are oriented and dispersed such that a photonic band gap cannot emerge;
- and
- (c) compressing said solid composite material into a compressed composite material in which the fine particles are dispersed such that the photonic band gap emerges, thereby obtaining a photonic crystal element.
