High-Q diamond microdisks for coupling to SiV quantum emitters

摘要

We demonstrate diamond microdisk optical cavities with record quality factors (Q ~ 1 × 105) at 737 nm wavelengths near the optical transitions of implanted silicon vacancy (SiV) quantum emitters. Simulations indicate that Q/V > 1.2 × 104 is possible in these structures with optimized dimensions.
