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. Crystals with a dual-periodic structure allow for great control in this effect and have potential to lead to very efficient, low threshold lasers. Several designs of one-dimensional photonic crystals were theoretically and numerically studied, which can be experimentally made with quantum dot photolithography. The results suggest that efficient light confinement in realistically achievable experimental structures is possible. The use of these structures is proposed for sensitive optical filters and efficient light emitting devices.

Light Propagation through a Dual-Periodic One-Dimensional Photonic Crystal
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. Crystals with a dual-periodic structure allow for great control in this effect and have potential to lead to very efficient, low threshold lasers. Several designs of one-dimensional photonic crystals were theoretically and numerically studied, which can be experimentally made with quantum dot photolithography. The results suggest that efficient light confinement in realistically achievable experimental structures is possible.
