Abstract Dissipative Kerr solitons from optical microresonators, commonly referred to as soliton microcombs, have been developed for a broad range of applications, including precision measurement, frequency synthesis, and ultra-stable microwave millimeter wave generation, all on chip. An important goal microcombs is self-referencing, which requires octave-spanning bandwidths detect stabilize the comb carrier envelope offset frequency. Further, detection locking spacings are often achieved using division by electro-optic modulation. The thin-film lithium niobate photonic platform, with its low loss, strong second- third-order nonlinearities, well large Pockels effect, ideally suited these tasks. However, challenging demonstrate this largely complicated Raman effects hindering reliable fabrication devices. Here, we entirely connected niobate. With appropriate control over microresonator free spectral dissipation spectrum, show that soliton-inhibiting suppressed, devices fabricated near-unity yield. Our work offers an unambiguous method generation strongly Raman-active materials. it anticipates monolithically integrated, self-referenced standards in conjunction established technologies, such periodically poled waveguides modulators,

We propose a reliable and simple approach for dispersion engineering in lithium niobate microring resonators (MRRs). With strong coupling-induced mode hybridization inverse design method, we overcome the large normal achieve broadband frequency comb coverage near 525 nm. adopt neural network method design, which outperforms traditional forward based on manual trial-and-error intuitive judgment.

We demonstrated an integrated high-Q cascaded Fabry-Perot (FP) resonator on lithium niobate insulator (LNOI) implemented by multi-Sagnac loop reflectors, which was fabricated femtosecond laser photolithography-assisted chemo-mechanical polishing (CMP). Compared with the that comprised only two Sagnac reflectors (SLRs), there is a significant Q factor enhancement in formed multi-SLRs. The loaded of measured to be 1.16 × 106, five-fold improvement compared state art same material platform.

Lithium tantalate on insulator (LTOI), taking advantage of high cost-effectiveness, ultra-low optical loss, and prominent electro-optic (EO) coefficient, shows great potential as an integrated waveguide-based platform for commercialization. Further research monolithic nonlinear source generators with tunable features is crucial in its early stages. Here, we fabricate low-loss microring resonators (intrinsic Q value above 4 × 10 6 ) via universal subtractive manufacturing. Both Kerr EO combs are realized based X-cut LTOI high-Q resonators. Specifically, elucidate the complicated synergy caused by a photorefractive (PR) effect thermo-optic modulation, observing soliton step using facile laser scanning technique. Furthermore, preliminary experimental result static comb also exploited 20 GHz free spectral range (FSR) resonator, verifying versatility this unique photonic on-chip microcomb generation.
