Webtion grating efficiency behavior under gamma radiation. The optical and functional performances required for space missions are essentially focused on wave-front quality, polarization sensitivity, and diffrac-tion efficiency. Two VPH candidate technologies were analyzed and compared: The first technology involves a dichromated gelatin (DCG ... 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…

WebApr 12, 2024 · Grating couplings (GCs) are one of the most convenient and efficient ways to interface off-chip components and PICs. Compared to edge couplers (ECs), GCs offer several advantages, including increased alignment tolerance, compatibility with wafer-scale testing, and the elimination of the need for deep facet etching or facet polishing [ 13 ].
