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.

“…Due to the high Q value of the microsphere cavity (often up to 10 8 ) [6], the intrinsic loss α and coupling loss of the WGM is very small. When αL1, T=t 2 <<1, the sum of the light field confined in the microsphere cavity is obtained, and the output part of the biconical taper optical fiber is obtained from the transmission model in figure 1:…”

“…In order to improve the sensitivity, a long FP cavity gas chamber is required and the volume is large. Optical WGM microcavity has an ultra-high quality factor (Q =10 8 ) and extremely small mode volume, so it has a very high power density (GW / cm 2 ), which makes it widely studied in basic science and application fields [3], such as nonlinear optics [4,5], Ultrlalow-threshold laser [6], enhanced up-conversion luminescence [7.8], optical frequency comb [9],soliton [10] and so on. The WGM microcavity has a much higher Q value than the FP cavity, which means that the loss of light in the cavity is extremely low.…”

In this paper, the principle of the methane gas enhanced the laser absorption by the WGM of high-Q microsphere was studied. A taper optical fiber was used as a coupler to couple 1653.72 nm laser into a microsphere with a optical fiber handle to form whispering gallery mode(WGM). The resonant wavelength of the microsphere cavity was changed to 1653.72 nm by injecting heating light along the handle, so that one resonant wavelength of the microsphere is just 1653.72 nm. The 1653.72 nm laser forms WGM continuously to surround the microsphere, and the effective optical path is greatly increased, which increases the interaction distance with methane, and thus the sensitivity of methane detection is improved. The results show that the microsphere with WGM can be used as a gas sensor.

“…Optical microcavities are integrated, low-loss, small resonant cavities that confine photons to tiny scales for long periods of time. The whisperingg gallery mode(WGM) microcavity has the characteristics of extremely high-quality factor (Q-value) and very small mode volume, so it has a very high power density (~GW / cm 2 ), which makes it widely studied in basic science and application fields [1], such as nonlinear optics [2,3], Ultrlalow-threshold laser [4], enhanced up-conversion luminescence [5.6], optical frequency comb and so on. In practical applications, WGM microcavities are often required to have a specific resonant wavelength or frequency, therefore, it is of great significance to study the frequency tuning of WGM microcavities.…”

Optical microcavity can confine photons to a tiny scale for a long time, and is an integrated, low-loss, small mode volume resonant cavity. The resonant frequency of WGM microcavities can be tuned by changing the refractive index and size of the cavity.Based on previous research, this paper proposes a micro-mushroom-shaped microcavity and illustrates the preparation method and characteristics of optical micro-mushroom cavities made of quartz materials. Through the photo-thermal effect, heated light was injected in along the handle of the micro-mushroom cavity, and the frequency tuning of the micro-cavity was thus achieved through the photo-thermal-optical conversion.
