Compton散射对光子晶体中光束自陷的影响

用相干函数法研究了Compton散射下圆形部分相干光束在全内反射光子晶体中的自陷行为。研究发现，散射使光谱中非相干成分和衍射效应降低，形成孤子的几率提高。传输中孤子振荡幅值、压缩程度、变化周期、半径均比散射前小，相干半径比散射前大，自聚焦起主导作用。

Influence of Compton scattering on self-trapping of optical beam in photonic crystal

Using the mutually coherent function，we study the influence of self-trapping of the circlar partially coherent optical beam in the total internal reflective photonic crystal（TIRPC）by Compton scattering. The result shows that the composition of the non-coherent optical beam in the optical spectrum and diffraction effect are decreased by Compton scattering，and the probability forming the soliton is raised. The vibration peak value of the soliton，compressed degree，variation cycle, and radius are less than those before the scattering，and the coherent radius is larger than that before the scattering. The self-focusing plays an important role in the optical beam propagation.
