我们报道了利用高Q回声走廊模实现高效全共振三波混频的实验观察。这些模式是在由LiNbO_3制成的毫米级环形腔中激发的。基于这种混频过程，我们实现了一种低噪声谐振式电光调制器。在9 GHz的相干微波泵浦下，用功率约为10 mW的接收器对光进行了有效的调制，实现了对纳瓦微波辐射的探测。文中还报道了33 GHz调制器样机的初步实验结果，对实验结果进行了理论解释，并讨论了该器件的可能应用。(C)2003年美国光学学会。
We report on the experimental observation of efficient all-resonant three-wave mixing using high-Q whispering-gallery modes. The modes were excited in a millimeter size toroidal cavity fabricated from LiNbO3. We implemented a low-noise resonant electro-optic modulator based on this wave mixing process. We observe an efficient modulation of light with coherent microwave pumping at 9 GHz with applied power of approximately 10 mW Used as a receiver, the modulator allows us to detect nanowatt microwave radiation. Preliminary results with a 33-GHz modulator prototype are also reported., We present a theoretical interpretation of the experimental results and discuss possible applications of the device.
