In optics, a diffraction grating is an optical component with a periodic structure that diffracts light into several beams travelling in different directions (i.e., different diffraction angles). The emerging coloration is a form of structural coloration. The directions or diffraction angles of these beams depend on the wave (light) incident angle to the diffraction grating, the spacing or distance be… WebSep 15, 2024 · High-order diffraction grating as light harvesters for solar energy conversion Gyo Hun Choi a 1 , Dong Jun Kim b 1 , Juyoung Moon a , Jong Hak Kim b , Jung Tae Park …
