Properties Investigation for Single-Defect Square-Lattice Photonic Crystal Slab Cavity in Crystal Material Application

Article Preview

Abstract:

Compact and high-quality cavities are essential building blocks in constructing nano-photonic systems and quantum information systems. So, it is important in understanding the properties of localized modes produced by disorder in two-dimensional photonic crystals cavity. Single defect square lattice photonic crystal slab cavity is taken as the investigation object, the relationship between structure parameters (lattice constant a, radius of hole r and slab thickness) and properties parameters (quality factor Qt, effective mode volume Vmode) is discussed for a optimization design of high performance cavity. The results of this investigation are useful reference for single defect square lattice photonic crystal slab cavity in photonic crystal material application.
