Quantum emitters such as the diamond nitrogen-vacancy (NV) center are basis for a wide range of quantum technologies. However, refraction and reflections at material interfaces impede photon collection, emitters' atomic scale necessitates use free space optical measurement setups that prevent packaging devices. To overcome these limitations, we design fabricate metasurface composed nanoscale pillars acts an immersion lens to collect collimate emission individual NV center. The metalens...
We present a general strategy for the inverse design of metasurfaces composed elementary shapes. use it to structure that collects and collimates light from nitrogen-vacancy centers in diamond. Such constitute scalable optical interfaces solid-state qubits, enabling efficient photon coupling into fibers eliminating free-space collection optics. The many-body shape optimization is practical alternative topology explicitly enforces material fabrication constraints throughout optimization,...
