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 Q value of 816±30 is achieved at λ =1.55 μm . This high- Q cavity will permit the realistic realization of spontaneous-emission modification and on–off optical switches.
