氮化铝（AlN）是一种很有吸引力的片上波长转换非线性光学材料。在这里，我们报告的光学频率梳产生高品质因数的AlN微谐振器集成在硅衬底上。通过设计波导结构以在电信波长处实现近零色散并优化四波混频的相位匹配，用单波长连续波泵浦激光器产生频率梳。此外，从我们的实验结果中提取了AlN的克尔系数（n（2））。(C)2013年美国光学学会
Aluminum nitride (AlN) is an appealing nonlinear optical material for on-chip wavelength conversion. Here we report optical frequency comb generation from high-quality-factor AlN microring resonators integrated on silicon substrates. By engineering the waveguide structure to achieve near-zero dispersion at telecommunication wavelengths and optimizing the phase matching for four-wave mixing, frequency combs are generated with a single-wavelength continuous-wave pump laser. Further, the Kerr coefficient (n(2)) of AlN is extracted from our experimental results. (C) 2013 Optical Society of America
