Tunable whispering gallery modes for spectroscopy and CQED experiments

Wolf von Klitzing, Romain Long, Vladimir S. Ilchenko +2

We have tuned the whispering gallery modes of a fused silica micro- resonator over nearly 1 nm at 800 nm, i.e.over half of a free spectral range or the equivalent of 10^6 linewidth…
