“…The dissipation rate of cavity mode can be effectively controlled by using gain competition, and the resonance evolution of the probe signal can be controlled while the pump remains unchanged [80]. Furthermore, recent studies have shown the parameter design of passively modelocking (ML) gain lasers [81]. It is found that the threshold of passively mode-locking is related to the gain and dispersion.…”

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.

“…The realization of a mode-locked laser based on the introduction of saturable absorber into chip-based laser has been confirmed on the silicon nitride integrated platform, 138 , 162 which can also provide a reference for the research of mode-locked lasers on an LNOI active light source platform. In addition, the multilongitudinal mode laser output based on REI-doped LNOI microcavity is also expected to achieve a mode-locked laser by introducing a saturable absorber or loading active regulation, such as electro-optic modulation to lock each longitudinal mode signal 163 . In the early stage, the application of the electro-optic effect of LN to realize mode-locked lasers was demonstrated on the erbium-doped LN weak waveguide 164 …”

Generation of high-speed laser pulses is essential for sustaining today’s global, hyper-connected society. One approach for achieving high spectral and temporal purity is to combine optical nonlinear materials with spectral filtering devices. In this work, a graphene-coated microresonator integrates a nonlinear material and a spectral filtering platform into a single device, creating a tunable GHz repetition rate mode-locked fiber laser. The graphene is directly synthesized on the non-planar surface of microresonator, resulting in a uniform, conformal coating with minimal optical loss in the device. The whispering gallery modes of the resonator filter the propagating modes, and the remaining modes from the interaction with graphene lock their relative phases to form short pulses at an elevated repetition rate relying on inter-modal spectral distance. Additionally, by leveraging the photo-thermal effect, all-optical tuning of the repetition rate is demonstrated. With optimized device parameters, repetition rates of 150 GHz and tuning of 6.1 GHz are achieved.
