Monolithic piezoelectric control of integrated soliton microcombs

Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Erwan Guillaume Albert Lucas, Wenle Weng, Arslan Sajid Raja, Jijun He, Miles Henry Anderson, Tianyi Liu

We demonstrate piezoelectric actuators monolithically integrated on ultralow-loss Si3N4 waveguides. Varying the voltage applied on the actuator allows tuning the microresonator, and is used to initiate, switch, stabilize and tightly phase lock the single s ...

Chip-based soliton microcomb module using a hybrid semiconductor laser

Tobias Kippenberg, Rui Ning Wang, Nicolas Volet, Junqiu Liu, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Jijun He

Photonic chip-based soliton microcombs have shown rapid progress and have already been used in many system-level applications. There has been substantial progress in realizing soliton microcombs that rely on compact laser sources, culminating in devices th ...

Microresonator Dual-Comb Coherent FMCW LiDAR

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Erwan Guillaume Albert Lucas, Anton Lukashchuk

We introduce a novel architecture for parallel frequency-modulated continuous wave (FMCW) laser ranging (LiDAR). Using dual soliton microcombs, we demonstrate a parallel distance measurement with 24 channels requiring only a single FMCW pump laser and cohe ...

Laser Self-Injection Locked Frequency Combs in a Normal GVD Integrated Microresonator

Tobias Kippenberg, Rui Ning Wang, Junqiu Liu, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Jijun He, John David Jost

We report the first demonstration of microresonator dark pulse generation by self-injection locking of a DFB laser to a Si3N4 microresonator with normal GVD. The 26 GHz repetition rate beatnote is characterized. (C) 2020 The Author(s) ...

Electrically driven photonic integrated soliton microcomb

Tobias Kippenberg, Maxim Karpov, Junqiu Liu, Hairun Guo, John David Jost, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Andrey Voloshin

We demonstrate via self-injection locking an electrically driven soliton micro-comb by coupling a multi-frequency laser diode to a chip-scale high-Q Si3N4 microresonator. This approach offers a pathway for an integrated and ultra-compact microcomb source f ...

Heteronuclear Soliton Molecules in Optical Microresonators

Tobias Kippenberg, Erwan Guillaume Albert Lucas, Wenle Weng, Tobias Herr

We enter the multi-stability regime of an optical microresonator to generate heteronuclear soliton molecules. Ultrafast electro-optical sampling reveals the bound structures of such soliton molecules, despite comprising solitons of dissimilar amplitudes, d ...

Physics of Dissipative Kerr Solitons in Optical Microresonators and Application to Frequency Synthesis

Erwan Guillaume Albert Lucas

Optical-frequency combs, that is spectra of equidistant coherent optical lines, have revolutionized the precision measurements of time and frequency. In 2007 a new method to generate optical frequency combs was discovered. In contrast to conventional gener ...

Thermo-refractive noise in silicon nitride microresonators

Tobias Kippenberg, Junqiu Liu, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, Guanhao Huang, Nils Johan Engelsen

Thermodynamic noises limit the frequency stability of resonators. Here, we present the first complete characterization of thermo-refractive noise in Si3N4 microresonators. The measurements are in good agreement with theoretical analysis and FEM simulation ...
