Abstract :
Photonic band gap (PBG) materials are artificial, periodic, dielectrics that enable engineering of the most fundamental properties of electromagnetic waves. In this paper, recent approaches to micro-fabrication of photonic crystals with a large 3D PBG centered near 1.5 microns are reviewed. The use of anomalous refraction in 3D photonic crystal thin films for the efficient trapping and absorption of light from an external source are introduced. Also a new type of PBG-quantum well hetero-structure in which excitons (bound electron-hole pairs) propagate are introduced
