摘要：

Optical whispering gallery mode (WGM) resonances have been observed in zinc oxide micro- and nanowire cavities. Using model calculations, the experimentally observed mode spectrum was reproduced. The effect has been observed for wire radii between 100 nm and 10 mu m corresponding to angular mode numbers from 1 to about 250. The whispering gallery effect was used to determine the refractive index of the wires as a function of the photon energy and temperature. Under high excitation conditions, WGM lasing was observed. Two methods for calculating the complex resonant modes are presented: a simple plane wave model and the numerical solution of the Helmholtz equation for the given resonator geometry.
