Abstract
A fiber-taper-coupled L-band microsphere laser was proposed and demonstrated. Er3+-doped tellurite glass was used to fabricate the microspheres. The microspheres were made by a novel spin method. The pump and emission light were coupled in and out of the microsphere modes with a tapered fiber. 975nm pumped L-band single/multi-mode microsphere lasers were demonstrated. The laser can be tuned in L-band. We call Er<sup>3+</sup>-doped microsphere laser as EDML.
