$Diffraction grating (DGTD) – Ansys Optics$

A blazed grating – also called echelette grating (from French échelle = ladder) – is a special type of diffraction grating. It is optimized to achieve maximum grating efficiency in a given diffraction order. For this purpose, maximum optical power is concentrated in the desired diffraction order while the residual power in the other orders (particularly the zeroth) is minimized. Since this condition can only exactly be achieved for one wavelength, it is specified for which blaze wavele… WebTheoretical and Experimental Demonstration on Grating Lobes of Liquid Crystal Optical Phased Array Demostración teórica y experimental de los lóbulos de rejilla de la matriz óptica en fase de ...
