Abstract
A photonic crystal device according to the present invention includes: a first dielectric substratehaving a first lattice structure, of which the dielectric constant changes periodically within a first plane; a second dielectric substratehaving a second lattice structure, of which the dielectric constant changes periodically within a second plane; and an adjustment device (pivot) for changing a photonic band structure, defined by the first and second lattice structures, by varying relative arrangement of the first and second lattice structures. The first and second dielectric substratesandare stacked one upon the other.
