Single InAs/GaAs quantum dots (QDs) are one of the most promising solid-state quantum emitters for applications such as quantum light generation and single-photon level nonlinear optics 1. Critical to ...
On target: bull's-eye-shaped grating helps extract photons A new optical grating shaped like a “bull’s-eye” that is extremely efficient at collecting photons from diamond nitrogen vacancy (NV) centres ...
