“…[19] Therefore, the optical microcavity has developed rapidly with its advantages of high quality (Q) factor and small mode volume, in low threshold lasers, sensors, cavity quantum electrodynamics, cavity optomechanics, and other fields. [20][21][22][23][24][25] Since the beginning of the revolution in optical microcavities, there have been a vast number of cavities, e.g., Fabry-Perot interferometers (F-P), [26][27][28][29][30] DOI: 10.1002/lpor.202300343 distributed Bragg reflectors (DFB), [31][32][33][34][35][36] distributed Bragg reflection (DBR) cavities, [37][38][39][40] whispering gallery mode (WGM) resonators, [41][42][43][44][45][46][47][48] scattering system (SS), [49][50][51][52][53] and deformation cavities. [54][55][56][57] These specific geometries endow these microcavities with, respectively, distinct lasing emission features in frequency, direction, mode, time, or angular momentum.…”

Control coupling and synchronization of lasers has become increasingly attractive for their applications in spectroscopy, imaging, sensing, secret communication, and optical networks. As complex microcavities emerge, more complicated light–matter interactions, along with the resulting distinct lasing emission behavior, is induced in these hybrid microcavities. This review summarizes the most important advances and current deep insights into the inherent relationship between the hybrid microcavity geometries and lasing behaviors, which are classified as the modulated lasing output freedom, including wavelength, angular momentum, mode, direction, and their multiple combinations. Finally, based on scientific research and practical application, the challenges and prospects of future development of hybrid microcavities are proposed, hoping to provide valuable inspiration for further optimizing hybrid microcavities to achieve low thresholds, small divergence angles, and single‐mode microcavity lasers.

“…Their recent work on LSHB suppression by introducing a pair of phase shifts in the basic sampled grating DFB structure [9] has shed light on solving the aforementioned issue through a viable approach. Comparing with the existing methods [10], not only this approach appears to be more effective, but it also bears the unique feature of fabrication readiness and easiness.…”
