Abstract
A new microcavity design is proposed and structures are realized with a two-dimensional photonic-crystal slab. The cavity consists of seven defect holes that encompass a hexagon and is designed to reduce vertical light leakage. From a direct transmission measurement, a value of is achieved at . This high- cavity will permit the realistic realization of spontaneous-emission modification and on–off optical switches.
