在四波混频实验中，我们证明了耦合谐振腔光波导（CROW）中高度增强的光学非线性。使用由200个基于线缺陷中的宽度调制光子晶体纳米腔的耦合谐振器组成的CROW，我们获得了超过10，000/W/m的有效非线性常数，这要归功于慢光传播与波长大小的腔实现的光的强空间限制相结合。(C)2011年美国光学学会
We demonstrate highly enhanced optical nonlinearity in a coupled-resonator optical waveguide (CROW) in a four-wave mixing experiment. Using a CROW consisting of 200 coupled resonators based on width-modulated photonic crystal nanocavities in a line defect, we obtained an effective nonlinear constant exceeding 10,000 /W/m, thanks to slow light propagation combined with a strong spatial confinement of light achieved by the wavelength-sized cavities.
