Abstract

Interest in dielectric microspheres is rapidly increasing because of their potential application in integrated photonics for filtering, dispersion management and all-optical switching. When doped with luminescent ions capable of laser oscillation, such as the rare-earths, these applications are extended to incorporate the potential for low threshold laser oscillation exploiting Whispering Gallery Modes (WGMs) to form cavities. This possibility has already been demonstrated in glass microspheres doped with different rare earth ions including Neodymium, of special relevance due to its high emission cross section at laser wavelengths and also because of the long lifetime of the metastable state (both facts ensuring low laser thresholds), that are presented in bulk materials. These two properties, and their possible modification during the fabrication procedure of microspheres, will dominate the final laser performance of the microspheres.
