Abstract

A nanopatterned polymer design for lasers using substructured gratings to achieve low threshold lasing is presented. The approach provides complete control over the balance between optical feedback and output coupling. Polymer lasers are fabricated by nanoimprint lithography with threshold densities as low as 16 W cm-2, half that of reference distributed feedback lasers with conventional gratings.
