Diffraction of a Gaussian<b> Beam</b> with <b>Limited Cross Section </b>by a Volume Phase Grating under Waveguide Mode Resonance
In this work, the diffraction of a Gaussian beam on a volume phase grating was researched theoretically and numerically. The proposed method is based on rigorous coupled-wave analysis (RCWA) and Fourier transform. The Gaussian beam is decomposed into plane waves using the Fourier transform. The numb...
