A tunable waveguide-coupled cavity design for scalable interfaces to solid-state quantum emitters
Photonic nanocavities in diamond have emerged as useful structures for interfacing photons and embedded atomic color centers, such as the nitrogen vacancy center. Here, we present a hybrid nanocavity design that enables (i) a loaded quality factor exceeding 50 000 (unloaded Q>106) with 75% of the...

| description | Photonic nanocavities in diamond have emerged as useful structures for interfacing photons and embedded atomic color centers, such as the nitrogen vacancy center. Here, we present a hybrid nanocavity design that enables (i) a loaded quality factor exceeding 50 000 (unloaded Q>106) with 75% of the enhanced emission collected into an underlying waveguide circuit, (ii) MEMS-based cavity spectral tuning without straining the diamond, and (iii) the use of a diamond waveguide with straight sidewalls to minimize surface defects and charge traps. This system addresses the need for scalable on-chip photonic interfaces to solid-state quantum emitters. |
