Anti-reflection (AR) coatings are widely used in a spectrum of optical and optoelectronic devices, such as monitors, car dashboards, optical lenses, photodiodes, and solar cells. Narrowband quarter-wavelength single-layer and broadband multilayer dielectric AR coatings are typically fabricated by expensive and low-throughput vapor deposition processes (e.g., sputtering). Inspired by the subwavelength-structured...
