We report a two-dimensional silicon photonic crystal structure that supports the self-collimation effect with large incident angles over a broad wavelength range. We theoretically and experimentally show the propagation light in the designed and fabricated structure without diffraction. Broadband large-angle self-collimation is observed in infrared wavelength.
我们报告了一种二维硅光子晶体结构，该结构在很宽的波长范围内支持大角度的自准直效应。我们从理论和实验上展示了在设计和制造的结构中光的传播没有衍射。在红外波长观察到宽带大角度自准直。
