High-speed laser frequency actuation is critical in all applications employing single frequency lasers orfrequency combs, and is prerequisite for phase locking, laser stabilization and stability transfer among mul-tiple optical carriers. Here, we demonstrate such capability for initiation, tuning and stabilization of solitonmicrocombs, by monolithically integrating piezoelectric AlN actuators on ultralow-loss Si3N4photonic circuits.The integrated AlN actuators feature bi-directional tuning with high linearity, operate with only 300 nWpower and exhibit flat actuation response up to megahertz frequencies, significantly exceeding bulk piezotuning bandwidth. This capability can be used to demonstrate soliton-based source for parallel continuous-wave frequency-modulated LiDAR, via synchronously tuning laser and microresonator. Our approach endowssoliton microcombs with integrated, ultralow-power-consumption, and fast actuation, significantly expandingthe repertoire of technological applications.

We demonstrate an architecture for massively parallel frequency-modulated continuous wave (FMCW) laserranging (LiDAR) by transferring linear chirps of a single narrow linewidth laser onto all soliton comb teeththough generation of a dissipative Kerr soliton in an integrated Si3N4microresonator. Furthermore, we introducea novel approach using dual soliton microcombs. We show a parallel distance measurement with 24 channelsrequiring only a single FMCW pump laser and coherent receiver for read-out

We demonstratea highly nonlinear hybrid waveguide platform based on infiltration of As2S3chalcogenide glass into silicon slot waveguides. The non linear properties of the hybrid waveguides have beenprecisely quantified via a bidirectional top-hat D-scan method, enabling a direct comparison between properties measured using different device geometries. We experimentally reporthybrid As2S3-Si slot waveguides with a two-photon absorption (TPA) figure of merit exceeding 2 at near infrared wavelengths. These waveguides allow for nonlinear phase shifts greater than π with minimal overall losses. These results pave the way for efficient and robust ultrafast all-optical devices and circuits in large-scale silicon photonics technology.
