Photon sieve

WebAn image of the photon sieve as lit by this beam is shown in Fig. 1(b). As ex-pected, the photon sieve focused the collimated light onto a focal spot 1 m away. The ratio of the total power in the focal spot to that incident upon the pho-ton sieve was 0.35%. The performance of the photon sieve was then evaluated in several ways, by focus- WebJul 8, 2024 · Testing of a fabricated four-step photon sieve showed efficiencies of ~50%, nearly five times the highest reported value for a photon sieve in the scientific literature. …
