V. Lefevreseguin et S. Haroche, TOWARDS CAVITY-QED EXPERIMENTS WITH SILICA MICROSPHERES, Materials science & engineering. B, Solid-state materials for advanced technology, 48(1-2), 1997, pp. 53-58
We present experiments performed on highly transparent silica microsph
eres used as very high Q optical resonators for cavity quantum electro
dynamics (CQED) studies. By coupling these microspheres to eroded opti
cal fibers and fiber tips, direct mapping of the whispering-gallery mo
des has been achieved and the mode quantum numbers have been assessed.
Low-threshold whispering-gallery modes lasers made with Nd-doped sphe
res are described and further CQED projects are proposed. (C) 1997 Els
