Abstract

In this paper, we employ a wavelet-based electromagnetic optimization algorithm to enhance multilevel diffractive lens performance. As we show in this paper, the optimized performance and iteration time is very much a function of the initial lens profile. To demonstrate this we analyze various types of initial profiles ranging from scalar-based lenses to flat and random structures. Additionally, we characterize the performance of replicated multilevel lenses fabricated using a soft lithographic technique known as nanoimprint lithography ( NIL) . Experimentalresults are presented.
