“…The WGM resonance in the Er 3+ /Yb 3+ co-doped glass microspheres was analyzed at different temperatures in the range of 290-380 K, and a resonance shift of 4.7 pmK −1 has been achieved [74]. For Yb 3+ /Pr 3+ -doped phosphate microsphere temperature sensor [71], the temperature uncertainty of WGM displacement is 0.4 K, which is 0.3 K higher than that of LIR technology (fig. 5).…”

Whispering gallery mode (WGM) cavities formed by dielectric structures have attracted intensive interest in various ﬁelds. The high-quality factor and smaller mode volume associated with the optical modes have inspired experiments in nonlinear optics, nanophotonics, and quantum information science. Moreover, it also gives rise to optical biosensors and other signiﬁcant applications. To further reduce the material loss of the resonator, optical gain materials, such as erbium and ytterbium, are doped into the dielectric structure to increase the nonlinear eﬀect and enhance the interaction between light and matter. Here in this review, we outline the most recent advancements in gain-doped optical WGM microcavities. Moreover, we introduce the dynamics of the gain in WGM resonators, the integration of gain media into WGM microcavities with various shapes, and the fabrication and applications of the gain microcavities. Also, the applications of the gain cavity based on the whispering-gallery mode have been introduced, e.g., ultra-sensitive sensors, low-threshold lasers, and high-performance optical systems.
