Reconfigurable Radiofrequency Photonic Filters Based on Soliton Microcombs
Tobias Kippenberg, Camille Sophie Brès, Jianqi Hu, Junqiu Liu, Arslan Sajid Raja, Jijun He
We demonstrate soliton based radiofrequency filters using a 104 GHz Si3N4 microresonator. The filter passband frequencies are widely reconfigured via inherent soliton states of perfect soliton crystals and two-soliton microcombs, without any external pulse ...
IEEE2020Dynamics and Applications of Dissipative Kerr Solitons
Optical frequency combs are optical sources, which spectrum consists of a series of equally spaced narrowband frequencies. They made an outstanding leap forward in the accuracy of optical frequency metrology and became an attractive tool for numerous appli ...
EPFL2020Spectral Properties of the Signal in Phase-Sensitive Optical Time-Domain Reflectometry with Direct Detection
Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Li Zhang, Xin Lu
The spectral properties of the Rayleigh backscattered traces measured by a phase-sensitive optical time-domain reflectometer (øOTDR) with direct detection are theoretically and experimentally analyzed. The spectrum of the measured øOTDR signal is found to ...

Tobias Kippenberg, Kun Shi, Junqiu Liu, Maxim Karpov, Arslan Sajid Raja, Anton Lukashchuk
We demonstrate sub-nanosecond wavelength switching, using a chip-based soliton microcomb and a semiconductor optical amplifier-based wavelength selector. 50-Gbps PAM4 transmission is achieved with discrete components and 25-Gbps NRZ with a photonic integra ...
IEEE2020Physics of Dissipative Kerr Solitons in Optical Microresonators and Application to Frequency Synthesis
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 ...

Optical frequency combs provide equidistant frequency markers and have applications that encompass fundamental Physics to Engineering. This tutorial will review the fundamental operational principles and latest development in the field of soliton microreso ...
IEEE2019Broadband Efficient Soliton Microcombs in Pulse-Driven Photonic Microresonators
Tobias Kippenberg, Junqiu Liu, Tobias Herr, Miles Henry Anderson, Sylvain Karlen
Broadband single-soliton based frequency combs, with a detectable repetition rate of 28 GHz, are efficiently generated through pulse-driving of a chip-based Si3N4 microresonator. We observe an influence of the pulse-driving rate on the comb mode linewidth. ...
IEEE2019Self-imaging of Azimuthal Intensity Petal Based on Orbital Angular Momentum Beams
Camille Sophie Brès, Jianqi Hu
We demonstrate for the first time azimuthal Talbot effect based on orbital angular momentum beams. The intensity petal is self-imaged in the azimuthal angle. We also draw the analogy between azimuthal and temporal Talbot effect. ...
2018Microresonator-based solitons for massively parallel coherent optical communications
Tobias Kippenberg, Victor Brasch, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Miles Henry Anderson
Solitons are waveforms that preserve their shape while propagating, as a result of a balance of dispersion and nonlinearity(1,2). Soliton-based data transmission schemes were investigated in the 1980s and showed promise as a way of overcoming the limitatio ...
