Parallel photopolymerization of microgear patterns

Bautista, Godofredo; Romero, Mary Jacquiline; Tapang, Giovanni; Daria, Vincent

Description

We report parallel two-photon photopolymerization of microgear patterns by exposing a photoresist to holographically generated optical vortices. The optical vortices are created by imparting a helical pitch onto the incident light using a programmable lithographic phase mask realized with a computer addressable phase-only spatial light modulator. By varying the phase levels of the spatial light modulator, the truncated helical phase of an optical vortex results in output intensity patterns that...[Show more]
