Boosting the photon-extraction efficiency of nanophotonic structures by deterministic microlenses

A novel concept for enhancing the photon-extraction efficiency of nanophotonics structures is presented. We apply in-situ electron beam lithography to enhance the single photon flux of single quantum dots by deterministically aligned microlenses.
