Dynamics of soliton self-injection locking in optical microresonators

Tobias Kippenberg, Junqiu Liu, Wenle Weng, Andrey Voloshin

Soliton microcombs constitute chip-scale optical frequency combs, and have the potential to impact a myriad of applications from frequency synthesis and telecommunications to astronomy. The demonstration of soliton formation via self-injection locking of t ...

Gain-switched semiconductor laser driven soliton microcombs

Tobias Kippenberg, Junqiu Liu, Erwan Guillaume Albert Lucas, Wenle Weng, Jijun He

Using phase-engineered coherent laser pulses produced by gain-switched semiconductor lasers, we generate low-power-threshold soliton microcombs whose repetition frequencies are in the X-band and K-band microwave ranges. (c) 2021TheAuthor(s) ...

Photonic chip-based resonant supercontinuum via pulse-driven Kerr microresonator solitons

Tobias Kippenberg, Junqiu Liu, Wenle Weng, Tobias Herr, Miles Henry Anderson

Supercontinuum generation and soliton microcomb formation both represent key techniques for the formation of coherent, ultrabroad optical frequency combs, enabling the RF-to-optical link. Coherent supercontinuum generation typically relies on ultrashort pu ...

Actuation bandwidth extension of an integrated piezo-optomechanical nanophotonic device

Tobias Kippenberg, Anat Siddharth, Junqiu Liu, Wenle Weng

We demonstrate a novel technique of contour-mode suppression of an integrated MEMS-photonic chip up to the first HBAR mode at 17 MHz. The flattened actuation response is critical to the development of compact LiDAR engine or low-noise frequency-agile laser ...

Laser soliton microcombs heterogeneously integrated on silicon

Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Wenle Weng, Zeyu Zhang, Chao Xiang, Zeyu Zhang

Silicon photonics enables wafer-scale integration of optical functionalities on chip. Silicon-based laser frequency combs can provide integrated sources of mutually coherent laser lines for terabit-per-second transceivers, parallel coherent light detection ...

Nanophotonic supercontinuum-based mid-infrared dual-comb spectroscopy

Luc Thévenaz, Tobias Kippenberg, Camille Sophie Brès, Junqiu Liu, Hairun Guo, Wenle Weng, Wolfgang Hänsel

High resolution and fast detection of molecular vibrational absorption is important for organic synthesis, pharmaceutical processes, and environmental monitoring, and is enabled by mid-infrared (mid-IR) laser frequency combs via dual-comb spectroscopy. Her ...

Wafer-scale fabrication of ultralow-loss silicon nitride nonlinear photonic circuits

Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Anat Siddharth, Maxim Karpov, Mikhail Churaev, Jijun He, Guanhao Huang, Wenle Weng, Arslan Sajid Raja

Recent advances in silicon nitride integrated photonics have achieved ultralow optical losses. Transferring this technology to standard commercial foundries, and merging it with silicon photonics via heterogeneous integration, will seed novel laser and qua ...

Resonant Supercontinuum Generation in Normal and Anomalous Dispersion

Tobias Kippenberg, Tobias Herr, Junqiu Liu, Wenle Weng, Miles Henry Anderson

We demonstrate broadband resonant supercontinuum generation based on stable bright soliton formation in Si3N4 microresonators with either anomalous or normal dispersion. The frequency combs have an electronically detectable repetition rate of 28 GHz, and s ...

Photonic chip-based resonant supercontinuum generation with intrinsic nonlinear filtering

Tobias Kippenberg, Junqiu Liu, Wenle Weng, Tobias Herr, Miles Henry Anderson

We demonstrate broadband soliton-based resonant supercontinuum generation in a chip-based microresonator. We show that the soliton possesses an intrinsic ability to filter RF noise transfer from the input pulses, which can be further improved with asynchro ...
