光学产生的自由载流子前沿可以引起频率和波矢量变化的光学跃迁，该自由载流子前沿沿着慢光光子晶体波导移动并与共同传播的信号波相互作用。凭借这些波导色散设计的灵活性，可以设想各种间接光子跃迁。通过前端传输的信号波经历带间跃迁，而从前端反射的信号波经历带内跃迁。给出了理论和实验结果。
Optical transition with changes of frequency and wave vector can be induced by optically generated free carrier fronts that move along a slow light photonic crystal waveguide and interact with a co-propagating signal wave. With the flexibility in dispersion designs of these waveguides, a variety of indirect photonic transitions can be envisaged. The signal wave transmitted through the front experience an inter-band transition, while the wave reflected from the front - an intra-band transition. Theory and experimental results are presented.
