Sub-nanosecond Optical Switching Using Chip-Based Soliton Microcombs

Tobias Kippenberg, 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 ...

Photonic chip-based soliton frequency combs covering the biological imaging window

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Martin Hubert Peter Pfeiffer, Anton Lukashchuk

Dissipative Kerr solitons (DKS) in optical microresonators provide a highly miniaturised, chip-integrated frequency comb source with unprecedentedly high repetition rates and spectral bandwidth. To date, such frequency comb sources have been successfully a ...

320 GHz Analog-to-Digital Converter Exploiting Kerr Soliton Combs and Photonic-Electronic Spectral Stitching

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Anton Lukashchuk, Viacheslav Snigirev, Grigorii Likhachev

We demonstrate a photonic-electronic analog-to-digital converter (ADC) offering a record-high acquisition bandwidth of 320 GHz. The system combines a high-speed electro-optic modulator with a Kerr comb for spectrally sliced coherent detection and is used f ...

Massively parallel coherent LiDAR using dissipative Kerr solitons

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Johann Emmeram Riemensberger, Erwan Guillaume Albert Lucas, Wenle Weng, Anton Lukashchuk

We demonstrate an architecture for massively parallel frequency-modulated continuous wave (FMCW) laser ranging (LiDAR) by transferring linear chirps of a single narrow linewidth laser onto all soliton comb teeth though generation of a dissipative Kerr soli ...

Megapixel per second hardware efficient LiDAR based on microcombs

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Johann Emmeram Riemensberger, Anton Lukashchuk

We show a novel architecture for massively parallel FMCW LiDAR based on multiheterodyne mixing of two triangular chirped soliton microcombs generated in integrated Si3N4 microresonators using a single laser source and a single coherent receiver. We demonst ...

Dual chirped microcomb based parallel ranging at megapixel-line rates

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Johann Emmeram Riemensberger, Anton Lukashchuk

Photonic integrated systems can be harnessed for fast and efficient optical telecommunication and metrology technologies. Here the authors develop a dual-soliton microcomb technique for massively parallel coherent laser ranging that requires only a single ...
