In this paper we present a novel mechanical pattern transfer process where
direct written perspex substrates are used as the master dies for embossing
. Using this nanofabrication process we have produced efficient diffractive
optical elements. The yield, repeatability and efficiency of the original
perspex samples are excellent and these characteristics are carried over in
to the replicas. At a smaller scale we have fabricated arrays of 60nm diame
ter nanopillars with excellent uniformity over large areas which have been
successfully applied in cell engineering applications.
