Chiral wave propagation manifold of the photonic quantum-ring laser

Abstract

A torus knot model is presented to analyze the chiral wave propagation of photonic quantum-ring lasers in a three-dimensional Rayleigh-Fabry-Perot toroidal cavity. The Rayleigh-Fabry-Perot cavity gives rise to peculiar multichromatic spectra with nonequal intermode spacings. In particular, the knot model analysis suggests a strange three-dimensional effective index ellipsoid for the cavity with a large birefringence of n(eff)(3D)(z)-n(eff)(2D)(x,y)approximate to0.4-0.5.
