Control of Modes Coupling, Selection and Enhancement in Wavelength-Scale Optical Microcavity Structures: Applications to Microlasers and Biosensing

Abstract

Recent advances and remaining challenges in spectral engineering of wavelength-scale optical microcavity structures supporting modes with narrow linewidths, wide mode spacing, directional emission, and greatly enhanced sensitivity to the environmental changes will be reviewed. General recipes for efficient control and manipulation of modes coupling and selective enhancement in such structures will be discussed
