WebA “diffraction grating” is an optical element that imposes a “periodic” variation in the amplitude and/or phase of an incident electromagnetic wave. 1 It thus produces, through … WebA binary phase grating capable of shaping an incident Gaussian beam to a flattop beam in a Fourier domain is designed iteratively. It is essential in grating design to consider the phases of diffracted waves by the grating, in addition to their amplitude uniformity and diffraction efficiency. The optimized grating phase produces the in-phase diffracted …

WebSep 17, 2024 · Binary phase grating is known to not have even order diffraction (O’Shea et al., 2004; Ma et al., 2024; Ma et al., 2024). By proper choice of the grating period, the energy in the reflected wave can be directed to one single direction.
