Design and Fabrication of Volume Holographic Gratings with Large Angular Bandwidth and High Diffraction Efficiency Qibin Feng1,a*, Yusong Guo2,b, Guoqiang Lv2,c 1Special Display and Imaging Technology Innovation Center of Anhui Province, National Engineering Laboratory of Special Display Technology, Academy of Opto-electric Technology, Hefei University of Technology, Hefei, Anhui, China country 2School of Instrument Science and Opto-electronics Engineering, Hefei University of Technology, Hefei, Anhui, China afengqibin@hfut.edu.cn, b1247438573@qq.com, cguoqianglv@hfut.edu.cn Keywords: volume holographic grating; diffraction efficiency; angular bandwidth; recording angle.
As a key component in a waveguide system, VHG presents important influence on field of view (FOV) and diffraction efficiency (DE).
When a VHG is illuminated by the beams with different wavelengths, the angle should satisfy Bragg condition as expressed by the following equation [14]: (11) Where λread and λrec are the wavelengths of the recording and readout beams, respectively. n1 and n2 are the refractive index of the material when recording and readouting, respectively.
