从固态单光子发射器(如量子点、分子或金刚石中的缺陷中心)有效收集光子是一项非常苛刻的任务。在这里,我们介绍了抛物面微天线制造的双光子直接激光写入,以提高收集效率,通过引导发射光到一个小的立体角。天线可以在预先选择的单光子发射器的位置处现场制造。
Efficient collection of photons from solid-state single-photon emitters, like quantum dots, molecules, or defect centers in diamond, is a very demanding task. Here, we introduce parabolic micro-antennas fabricated by two-photon direct laser-writing to enhance the collection efficiency by directing emitted light into a small solid angle. The antennas can be fabricated on-site at the position of a pre-selected single-photon emitter.
