| 1. A photonic crystal device comprising:
a first dielectric substrate having a first lattice structure, of which the dielectric constant changes periodically within
a first plane;
a second dielectric substrate having a second lattice structure, of which the dielectric constant changes periodically within
a second plane; and
an adjustment device 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,
wherein the first and second dielectric substrates are stacked one upon the other,
wherein the first dielectric substrate includes a conductor line, coplanar lines or a slot line
wherein the first dielectric substrate includes a conductor line, and
wherein the first lattice structure is defined by a periodic arrangement of openings that have been cut through the conductor
line.
