Fabrication of photonic crystals with different surface orientation by holographic lithography
全息制作不同晶面取向光子晶体模板

A diamond_like structure, which has a large complete photonic band gap and needs only a low refractive index contrast to open the complete photonic band gap, have been fabricated using four umbrellalike beams. By use of special prism to match the beams, diamond_like crystals with special surface orientations have been fabricated. The capability and feasibility of this method have been demonstrated by the fabrication of long_range ordered diamond_like microstructures with (114) and (110) surface orientation. The fabrication of large crystals with adjustable surface orientations will be advantageous to the systematic investigation of photonic properties such as negative reflection etc.
