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- WebAug 31, 2005 · Photon sieves can be simply designed to any conic, apodization and operating bandwidth. The photon sieve is easier to fabricate than the better known Fresnel zone plate as a single substrate can be used since there are no connected regions requiring support. Presented here are results of prototypes capable of diffraction-limited imaging …
