Abstract

Fractal Zone plates and optical pin sieves are designed and their focusing properties are analyzed using scalar diffraction formula. It is found that these zone plates offer better control on beam parameters compared to Fresnel Zone plates. These zone plates are then fabricated on to quartz substrates using UV lithography and the results are confirmed.
