    • Electromagnetic radiation is input into a photonic crystal having a shock wave propagating within, wherein interactions between the shock wave and the incident electromagnetic radiation provide for the modification of frequency and bandwidth associated with input electromagnetic radiation. Modifications in frequency of the electromagnetic radiation are on the order of the gap size with 100% efficiency in some cases. Additionally, the bandwidth associated with the electromagnetic radiation is increased or decreased by orders of magnitude based on such interactions. High amplitudes are trapped at the shock front for a controllable period of time, allowing for the controlled manipulation of pulses of light. Lastly, the incorporation of deliberately designed crystal defects and non-linear materials results in the conversion of all the energy in the defect band upwards in frequency if the highest group velocity is less than the shock wave speed.
    • 将电磁辐射输入到具有在其内部传播的冲击波的光子晶体,其中冲击波和入射电磁辐射之间的相互作用提供与输入电磁辐射相关联的频率和带宽的修改。 在某些情况下,电磁辐射频率的变化在间隙大小的数量级上具有100%的效率。 此外,与电磁辐射相关联的带宽基于这种相互作用增加或减少数量级。 高振幅被捕获在冲击前端一段可控的时间,从而允许对光脉冲的受控操纵。 最后,如果最高组速度小于冲击波速度,故意设计的晶体缺陷和非线性材料的结合导致在缺陷带中的所有能量在频率上向上的转换。
