在GaN和AlN平板波导中观察到相位匹配的光学二次谐波（SH）产生。相位匹配是通过波导模式色散实现的。通过调节光参量放大器的输出波长，在可见光谱范围内观察到了几个相位匹配的SH峰。峰位置与使用膜和衬底材料的色散折射率计算的值一致。(C)1999年美国物理学会。[S0556-2821（99）03904-1]。
Phase-matched optical second-harmonic (SH) generation was observed in GaN and AlN slab waveguides. Phase matching was achieved by waveguide modal dispersion. By tuning the output wavelength of an optical parametric amplifier, several phased-matched SH peaks were observed in the visible spectrum covering blue to red wavelengths. The peak positions are in agreement with the values calculated using the dispersive refractive indices of the film and substrate materials. (C) 1999 American Institute of Physics.
