Holographically Generated Volume Grating

Holographic generated volume gratings, with a thickness much larger than the wavelength, normally exhibit a narrow bandwidth for the particular design wavelength and angle. Following the two-beam interference exposure process, a volume grating inside fused silica is generated and simulated with the rigorous Fourier modal method (FMM) in VirtualLab Fusion. Both the spectral and angular dependent reflection property of the grating are analyzed.
