Photon sieve
WebJul 24, 2024 · Regular photon sieve (PS) may only have up to ~25% transmission of light. The low transmission limits its applications in many fields such as satellite remote … WebJun 1, 2007 · A photon sieve is based on a Fresnel zone plate, which contains concentric bright and dark rings. In a conventional photon sieve, the holes are centred on the bright zones. Andersen's photon sieve however achieves the same optical performance by positioning larger "antiholes" on dark regions, which makes the component easier to …
