Soliton Generation in a Gallium Phosphide Photonic-Crystal Fabry-Perot Microresonator
Tobias Kippenberg, Nikolai Kuznetsov, Alisa Davydova, Alberto Nardi, Miles Henry Anderson
Ring resonators have proven to be extremely successful for generation of temporal dissipative Kerr solitons, but their dispersion engineering is limited. We present a photonic-crystal Fabry-Perot resonator with record-high quality factors in gallium phosph ...
IEEE2023High density lithium niobate photonic integrated circuits
Tobias Kippenberg, Rui Ning Wang, Anat Siddharth, Mikhail Churaev, Nikolai Kuznetsov, Zihan Li, Junyin Zhang, Zelin Tan
Photonic integrated circuits have the potential to pervade into multiple applications traditionally limited to bulk optics. Of particular interest for new applications are ferroelectrics such as Lithium Niobate, which exhibit a large Pockels effect, but ar ...
NATURE PORTFOLIO2023A photonic integrated continuous-travelling-wave parametric amplifier
Tobias Kippenberg, Rui Ning Wang, Nikolai Kuznetsov, Junqiu Liu, Jijun He
The ability to amplify optical signals is of pivotal importance across science and technology typically using rare-earth-doped fibres or gain media based on III-V semiconductors. A different physical process to amplify optical signals is to use the Kerr no ...
NATURE PORTFOLIO2022Time-continuous Travelling-Wave Optical Parametric Amplification in a Photonic Circuit
Tobias Kippenberg, Rui Ning Wang, Nikolai Kuznetsov, Junqiu Liu, Jijun He
We demonstrate a traveling wave parametric amplifier in a photonic Si3N4 integrated spiral waveguide of 2.0 m length with footprint 3x5 mm. We achieve net gain of 7 dB on-chip and 2 dB fiberto-fiber in the optical C-band. (C) 2022 The Author(s) ...
