Abstract

We report the photothermal properties of a photonic crystal nanofiber (PhCN) cavity, which is fabricated using a femtosecond laser ablation technique, under ultra-high vacuum conditions. The results show that by launching a non-resonant guided light, the stopband of the PhCN, along with the cavity modes, can be tuned at a rate of 250 GHz (0.5nm)/mW. Moreover, due to the thermal self-locking effect of a resonant light, a cavity mode with a finesse of 25 can be tuned over a few free spectral ranges using only a few μW of guided light. As an enabling step, we demonstrate a dual-mode locking scheme to thermally stabilize a cavity mode to the atomic line for single atom–based cavity quantum electrodynamics experiments.
