Semiconductor laser chip stabilization by Si3N4 microresonator and Kerr comb generation

Tobias Kippenberg, Andrey Voloshin, Mirjam Pfeiffer

The experimental study of the InPlaser diode stabilization by high-Q Si3N4 microresonator is presented. We demonstrate how this stabilized laser diode considered as a pump laser may be used for optical frequency comb generation in the same microresonator. ...

Full C and L-Band Transmission at 20 Tbit/s Using Cavity-Soliton Kerr Frequency Combs

Tobias Kippenberg, Victor Brasch, Maxim Karpov, Arne Kordts, Mirjam Pfeiffer

Temporal soliton formation in a Kerr-nonlinear optical micro-resonator leads to a coherent frequency comb covering the C and L-band. We demonstrate WDM transmission with 94 comb lines and an aggregate data rate of 20 Tbit/s. ...

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. ...

Factors controlling variability in the oxidative capacity of the troposphere since the Last Glacial Maximum

Jed Oliver Kaplan, Mirjam Pfeiffer

The oxidative capacity of past atmospheres is highly uncertain. We present here a new climate-biosphere-chemistry modeling framework to determine oxidant levels in the present and past troposphere. We use the GEOS-Chem chemical transport model driven by me ...

The effect of abrupt climatic warming on biogeochemical cycling and N2O emissions in a terrestrial ecosystem

Jed Oliver Kaplan, Mirjam Pfeiffer

The large, rapid increase in atmospheric N2O concentrations that occurred concurrent with the abrupt warming at the end of the Last Glacial period might have been the result of a reorganization in global biogeochemical cycles. To explore the sensitivity of ...

A model for global biomass burning in preindustrial time: LPJ-LMfire (v1.0)

Jed Oliver Kaplan, Mirjam Pfeiffer

Fire is the primary disturbance factor in many terrestrial ecosystems. Wildfire alters vegetation structure and composition, affects carbon storage and biogeochemical cycling, and results in the release of climatically relevant trace gases including CO2, C ...

Response of terrestrial N2O and NOx emissions to abrupt climate change

Jed Oliver Kaplan, Mirjam Pfeiffer

Being a potent greenhouse gas, N2O emitted by the terrestrial biosphere during abrupt climate change events could have amplified externally forced warming. To investigate this possibility, we tested the sensitivity of terrestrial N2O emissions to an abrupt ...
