Abstract
We demonstrate efficient upconversion of sub-THz radiation into the optical domain in a high-Q whispering gallery mode resonator with quadratic optical nonlinearity. The 5x10^{-3} power conversion efficiency of continuous wave 100GHz signal is achieved with only 16 mW of optical pump.
This revision is limited to discussion of only optical WGMs coupled with the external Rf field. Discussion of RF WGMs is now posted separately
