摘要
We investigate optical transformations by three-dimensional photonic crystals fabricated via holographic lithography. Large-area three-dimensional photonic crystal structures are created by multiple-beam interference in photosensitive materials. We perform calculations of the optical transfer function for monochromatic incident light. Our approach is based on three-dimensional vector rigorous coupled-wave approach, which allows modeling the dynamic interaction of light waves generated by diffraction inside a crystal grating. We analyze the Bragg-conditioned energy transfer for different crystal structures and address the influence of the refractive index contrast. Diffractive-optical properties of the fabricated crystals are investigated by laser scanning and monitoring the transmitted light in three-dimensional angular space. The scan results agree well with the modeling predictions for different crystals and recording photopolymers. (C) 2013 AIP Publishing LLC. [http://dx.doi.org/10.1063/1.4816473]
