Abstract

Recent advances in material science have sparked tremendous growth in the field of photonic crystals [1]. These novel optical materials consist of periodic arrays of dielectric material exhibiting strong Bragg-scattering of electromagnetic waves, which in certain cases leads to the formation of a photonic band gap (PBG). Under suitable circumstances with respect to material composition, topology and lattice symmetry, forbidden frequency ranges may be created over which ordinary propagation of electromagnetic radiation is absent irrespective of the direction of propagation, while, at the same time, the material is non-absorbing. The ability to tailor electromagnetic dispersion relations and the associated photonic mode structures through suitably engineered photonic crystals facilitates a new approach to applications such as low threshold, high efficiency micro-lasers, high modulation speed laser systems, ultrafast all-optical switches, all-optical micro-transistor and the integration of such devices onto an optical micro-chip.
