Description
By embedding rare-earth ions in lithium niobate thin film, the authors report a novel method to dynamically control the Purcell effect of rare-earth ions in LNOI cavities in a wide frequency range and fast speed.
The Purcell enhancement hence increases the emission rate of the coupled rare-earth ions. The authors hence provide evidence of detecting single Yb3+ ions.
