Abstract
The effect of coating thickness on photon tunneling behavior was investigated by measuring lasing spectra from a dielectric inner-coated cylindrical capillary filled with a dye-doped liquid. The lasing spectra showed a blueshift as the coating thickness decreased due to an enhanced photon tunneling probability of whispering gallery modes (WGMs). Cavity quality factors Q were quantitatively estimated from the center wavelengths and compared to those deduced by the WKB approximation model as well as a simplified multiple scattering formalism. The validity and limitation of two models were discussed at various coating thicknesses.
