This paper demonstrates a thermally and electrically tunable hollow glass microsphere resonant cavity filled with dye-doped nematic liquid crystal. We controlled the orientation of in-sphere liquid crystal and encapsulated it with polydimethylsiloxane film. The typical whispering gallery modes (WGMs) lasing spectra were obtained under a pulsed laser pump and the effects of the temperature and electric field on the peaks wavelengths were studied. The WGM spectra present a blueshift significantly with increasing temperature and electric field due to the decrease in the effective refractive index.
