摘　　要：对利用光辐照技术在铌酸锂(LiNbO3:Fe)晶体中制作大面积小周期(2+1)维光折变光子晶格进行了详细实验研究。采用波长为532nm激光在晶体中成功地构造了面积为5.7mm2、晶格周期为13μm×13μm的(2+1)维光折变光子晶格。给出了实现大面积、小周期(2+1)维光折变光子晶格制作的实验参数,并对在实验中需要注意的问题进行了详细说明。The （2 ＋ 1） -dimensional large-area little-period photonic lattices of photorefractive fabricated employing optically-induced method in LiNbO3 ： Fe crystal is experimentally investigated. The （2＋1） -dimensional large-area little-period photonic lattices of photorefractive, which lattice distance is 13μm× 13μm and area is about 5. 7mm^2, has been fabricated successfully when adopting the laser which wavelength is 532nm. The results show that the index distribution of the fabricated photonic lattices is strongly dependent on the polarization states and irradiation time. The optimized parameters of fabricating large-area and little period structure photonic lattices are presented, and the points need to pay attention to experimentation are narrated in detail.
