TLDR
The conventional Fabry-Perot resonator is shown to be a special case of this general class of cavities that have uniform polygonal geometries and have significant applications in a wide variety of optical devices.Abstract:
A general class of multifacet optical resonators that have uniform polygonal geometries is described. Expressions for the transmission of light through classical refractive escape from the cavities are presented. The conventional Fabry–Perot resonator is shown to be a special case of this general class of cavities. The effects of absorption and scattering of optical radiation on the transmission properties and cavity-quality factors are analyzed. These resonator structures have significant applications in a wide variety of optical devices.read more

High-Q measurements of fused-silica microspheres in the near infrared.
TL;DR: The observed independence of Q from wavelength indicates that losses for the WGM's are dominated by a mechanism other than bulk absorption in fused silica in the near infrared.
