THE SPECTRUM OF MICRODISK LASERS

A model for quantitative analysis of microdisk laser emission spectra is presented. Conformal mapping is used to determine radial and azimut hal eigenvalues, eigenvectors, and cavity Q corresponding to leaky opt ical resonances in an optically transparent dielectric disk. The effec ts of gain and loss in a microcavity active medium are also included i n the model. Our results compare well with experimental data obtained from,an InGaAs/InGaAsP quantum well microdisk laser of radius R=0.8 mu m. (C) 1996 American Institute of Physics.
