New #openaccess article online: A diamond #Nanophotonic interface with an optically accessible deterministic electronuclear spin register.
By implanting 117Sn, a fibre-packaged nanophotonic diamond waveguide with optically addressable hyperfine transitions separated by 452 MHz is demonstrated. This enables the formation of a spin-gated optical switch and achieving a waveguide-to-fibre extraction efficiency of 57%.
