Anti-reflective coating by 3D PDMS stamping using two-photon lithography master
Source abstract
Abstract
Abstract A method for the repeated manufacture of nanoscale optical features is presented. The method utilizes nanoscale 3D printing technology to create master structures that can be rapidly duplicated using a soft lithography method. Stamps are made of polydimethylsiloxane (PDMS) from the master structure and then inked with a mixture of nanoparticles and epoxy to create a 3D negative of the master structure. To demonstrate this method, an array of pyramids comprised of germanium (Ge) nanoparticles and epoxy were produced to function as an antireflective coating in the short wave infrared (SWIR). The antireflective array was tested and compared to 5 commercial low reflective coatings.
