We demonstrate efficient upconversion of subterahertz radiation into the optical domain in a high-Q whispering gallery mode resonator with quadratic optical nonlinearity. The 5x10(-3) power conversion efficiency of a cw 100 GHz signal is achieved with only 16 mW of optical pump.
我们展示了在具有二次光学非线性的高Q回音壁模式谐振器中，将亚太赫兹辐射高效上转换到光学领域。仅用16毫瓦的光泵浦就实现了连续波100吉赫兹信号5×10⁻³的功率转换效率。
