Abstract

There has been much interest in the use of microcavities or dielectric structures to modify the rate or spatial pattern of spontaneous emission. The modification of spontaneous emission is of interest to the realization of very low threshold lasers. Recently, Ho et al. demonstrated photonic-wire microcavity ring semiconductor lasers with very low thresholds.¹ The photonic wire laser is a microcavity ring laser formed by a strongly guided single-mode semiconductor waveguide. It is of interest to investigate the modification of spontaneous emission in such photonic-wire laser cavity.
