title = "The formation of high-Q polygon modes in weakly perturbed microdisks on thin-film lithium niobate and its applications",
abstract = "Mode trimming of suitable dispersion in a high-Q microresonator is of vital importance for lots of photonic applications ranging from Kerr soliton comb generation, single-frequency lasing to nonlinear frequency conversion. However, almost all the dispersion engineering and mode trimming cannot be tuned once the resonator structure is made. To overcome this difficulty, weak perturbation was introduced into a circular lithium niobate (LN) microdisk for the formation of polygon modes by a coupled tapered fiber. Various polygon modes with different spatial field distributions and star mode can be formed by tuning the pump wavelength and the coupling position. Thanks to the small spatial modal overlap between the polygon modes and the whispering gallery modes (WGMs), densely distributed WGM families were avoided to be excited under polygon-mode optical pump. Therefore, single-frequency/dual-wavelength microlasers have been demonstrated with narrow linewidths in weakly-perturbed erbium-doped LN microdisks, and Kerr soliton microcomb has been generated in the telecom band in a normal-dispersion LN microdisk by mode trimming through the excitation of the anomalous-dispersion polygon modes.",
