Abstract

The present planar photonic bandgap structures achieve improved control over radiation losses by employing layered dielectric structures. These structures control radiation losses incurred in connection with planar photonic bandgap structures and waveguides, waveguide bends, waveguide crossings, filters, switches and fiber-coupling structures in which such planar photonic bandgap structures are used.
