Coupling of silicon-vacancy centers to a single crystal diamond cavity
Optical coupling of an ensemble of silicon-vacancy (SiV) centers to
single-crystal diamond microdisk cavities is demonstrated. The cavities are
fabricated from a single-crystal diamond membrane generated by ion implantation
and, electrochemical liftoff followed by homo-epitaxial overgrowth. Whispering
gallery modes which spectrally overlap with the zero-phonon line (ZPL) of the
SiV centers and exhibit quality factors ~2200 are measured. Lifetime reduction
from 1.8 ns to 1.48 ns is observed from SiV centers in the cavity compared to
those in the membrane outside the cavity. These results are pivotal in
developing diamond integrated photonics networks
