Soliton Kerr Frequency Combs Generated in Integrated Photonic Chips

Victor Brasch

In 2007 a new method to generate optical frequency combs was discovered. In contrast to conventional frequency combs which are generated from pulsed laser sources, these Kerr frequency combs (also known as microresonator frequency combs) are generated enti ...

50 Tbit/s Massively Parallel WDM Transmission in C and L Band Using Interleaved Cavity-Soliton Kerr Combs

Tobias Kippenberg, Victor Brasch, Maxim Karpov, Martin Hubert Peter Pfeiffer, Mirjam Pfeiffer, Arne Kordts

Interleaving two soliton Kerr combs we generate 179 carriers for WDM transmission and demonstrate transmission of a data stream of 50 Tbit/s over 75 km. This is the highest data rate achieved with a chip-scale comb source. ...

Bringing short-lived dissipative Kerr soliton states in microresonators into a steady state

Tobias Kippenberg, Victor Brasch, Michael Wolfgang Geiselmann, Martin Hubert Peter Pfeiffer

Dissipative Kerr solitons have recently been generated in optical microresonators, enabling ultrashort optical pulses at microwave repetition rates, that constitute coherent and numerically predictable Kerr frequency combs. However, the seeding and excitat ...

Multi-Terabit/s Transmission Using Chip-Scale Frequency Comb Sources

Tobias Kippenberg, Victor Brasch, Tobias Herr

Chip-scale frequency comb sources are likely to become key elements of future terabit/s optical transceivers. We investigate and demonstrate the viability of different comb generation schemes for transmission at multiterabit/s data rates. ...

Frequency-comb-assisted broadband precision spectroscopy with cascaded diode lasers

Tobias Kippenberg, Victor Brasch, Michael Wolfgang Geiselmann, Junqiu Liu, Hairun Guo, Martin Hubert Peter Pfeiffer, Arne Kordts

Frequency-comb-assisted diode laser spectroscopy, employing both the accuracy of an optical frequency comb and the broad wavelength tuning range of a tunable diode laser, has been widely used in many applications. In this Letter, we present a novel method ...

Coupling Ideality of Integrated Silicon Nitride Microresonators for Nonlinear Photonics

Tobias Kippenberg, Victor Brasch, Junqiu Liu, Maxim Karpov, Hairun Guo, Martin Hubert Peter Pfeiffer, Arne Kordts

Integrated microresonators are essential building blocks of linear and nonlinear photonic devices. Here we show that the performance of high-Q silicon nitride microresonators for nonlinear photonics strongly depends on the ideality of their coupler design. ...

Silicon-organic hybrid (SOH) devices and their use in comb-based communication systems

Tobias Kippenberg, Victor Brasch, Tobias Herr

Advanced wavelength-division multiplexing (WDM) requires both efficient multi-wavelength light sources to generate optical carriers and highly scalable photonic-electronic interfaces to encode data on these carriers. In this paper, we give an overview on o ...

Self-Referenced, Chipscale Kerr Frequency Comb without External Broadening

Tobias Kippenberg, Victor Brasch, Michael Wolfgang Geiselmann, Erwan Guillaume Albert Lucas, John David Jost

A Kerr frequency comb generated in an integrated silicon nitride microresonator is self-referenced using the 2f-3f approach. With an intrinsic bandwidth of two-thirds of an octave no additional, external broadening of the spectrum is required. ...

Raman Self-Frequency Shift of Dissipative Kerr Solitons in an Optical Microresonator

Tobias Kippenberg, Victor Brasch, Michail Zervas, Michael Wolfgang Geiselmann, Maxim Karpov, Hairun Guo, Martin Hubert Peter Pfeiffer, Arne Kordts

We experimentally observed the Raman-induced self-frequency shift of high-intensity dissipative Kerr solitons in high-Q silicon nitride microresonators. The Raman redshift is linearly dependent on the pump-frequency-detuning, associated with the tunability ...

Raman Self-Frequency Shift of Dissipative Kerr Solitons in an Optical Microresonator

Tobias Kippenberg, Victor Brasch, Michail Zervas, Michael Wolfgang Geiselmann, Maxim Karpov, Hairun Guo, Martin Hubert Peter Pfeiffer, Arne Kordts

The formation of temporal dissipative Kerr solitons in microresonators driven by a continuous-wave laser enables the generation of coherent, broadband, and spectrally smooth optical frequency combs as well as femtosecond pulse sources with compact form fac ...
