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- WebThe photon sieve is a thin film of titanium filled with randomly oriented pinholes. By placing the photon sieve close to a transmissive LCD panel, the diffraction angle of the light field can be considerably enhanced.
