Paper Abstract

Lateral confinement for cylindrical micro-resonator light emitters improves the ratio of the number of the axial resonant modes to the number of the spontaneous emitting lateral modes. We have observed resonator-behaviour of cylindrical micro-structures, whose lateral surfaces were coated with coaxial MgO/ZrO2 and a-Si/SiOχ Braggre flectors. Glass rods with circularly shaped basal planes and ZnO wires with hexagonally shaped basal planes were used as cavity material. Bragg-reflectors were deposited using pulsed laser deposition and plasma enhanced chemical vapour deposition at the lateral surface of the ZnO wires and the glass rods. The optical properties of the Bragg-reflectors were investigated using a confocal micro-reflectometer, spatially resolved spectroscopic ellipsometry technique, and spatially resolved cathodoluminescence measurements.
