利用全内反射和带隙效应的结合，在混合光子晶体光纤的零色散波长附近发射飞秒脉冲，实验证明了两个不同光子带隙中光谱成分之间的非线性相互作用。结果表明，初始脉冲频谱变宽，在不同的带隙中产生窄带共振辐射，而不是在泵浦波长处负责引导的带隙。在泵浦引导带隙中，共振辐射的光谱强度比加宽脉冲的谱强度低2.7 dB。
Nonlinear interaction between spectral components in two different photonic bandgaps is experimentally demonstrated by launching femtosecond pulses near a zero-dispersion wavelength of a hybrid photonic crystal fiber, which guides by a combination of total internal reflection and bandgap effects. It is demonstrated that the initial pulse becomes spectrally broadened, and narrowband resonant radiation is generated in a different bandgap from the one responsible for guiding at the pump wavelength. The spectral intensity of the resonant radiation peaks at 2.7 dB below that of the broadened pulse in the pump-guiding bandgap.
