Abstract
Photonic crystal structures are a light analog of electronic semi-conductors. The electromagnetic spectrum of these crystals exhibits photonic band gaps where light propagation is forbidden. This attribute has led to an increased interest in photonic crystals as well as numerous optical applications. Further, the anomalous dispersion properties of these crystals allow for the tailoring of materials in which light propagates at very slow speeds. The system can be considered as a coupled-resonator optical waveguide (CROW): photonic bands with abnormally small dispersion are created due to the interaction of long-lived states in the cavity regions via weak coupling across tunneling barriers. Unlike previous CROW implementations, the proposed structures can be fabricated with interference photolithography (holography) sidestepping the issue of resonator-to-resonator fluctuation of the system parameters. These structures can also be implemented in photonic crystal slab waveguides.
