Abstract

High-power whispering-gallery modes (WGMs) emitted from microcavity lasers have attracted attention for many applications, such as optical signal processing, spectroscopy, optical sensors, and large-bandwidth optical communications. In this paper, we present a simple approach for controlling the output WGMs of erbium-doped silica microsphere lasers. With the presented scheme, accurate adjustment of the coupling gap between the collection fiber taper and the spherical surface allows us to select different single modes of the microsphere laser or different multimode configurations (also functions of the waist diameter of taper and the Er-doped concentration). The nonlinear frequency shift of the microsphere cavity as a function of intracavity power has also been studied. The high intensity and high side mode suppression ratio of the obtained single WGM are suitable for spectroscopy, optical sensors, and communications.
