Bright squeezed light via second harmonic generation in a whispering-gallery mode resonator

摘要

We investigate the conditions necessary for bright squeezed light generation through second harmonic generation inside a crystalline whispering-gallery mode resonator. We show that the variance of a coherent mode can be reduced by a factor of 9 due to low loss through a nonlinear medium. This results in a one-step process that can generate efficient bright squeeze light at a desired wavelength.
