Abstract

A simple approximation is developed for solving the "whispering gallery modes" of a microdisk laser structure using conformal transformation and the WKB approximation. Using this method the spontaneous emission coupling factor of microdisk lasers is estimated. The result predicts a β value of the order of 10-1.
