Unconventional time-bandwidth performance of resonant cavities with nonreciprocal coupling
Camille Sophie Brès, Davide Grassani, Ivan Cardea, Kosmas Tsakmakidis
The time-bandwidth limit is a mathematical tenet that affects all reciprocal resonators, stating that the product of the spectral bandwidth that can couple into a resonant system and its characteristic energy decay time is always equal to 1. Here, we devel ...
2021Multi-gas spectroscopy using tailored mid-IR dispersive wave generated in Si3N4 waveguide
Camille Sophie Brès, Davide Grassani, Eirini Tagkoudi
We demonstrate simultaneous detection of acetylene, methane and ethane using milliwatt-level dispersive-wave generated in a Si3N4 waveguide covering 2900 cm-1-3380 cm-1 spectral region. This simple mid-IR absorption spectroscopy scheme achieves hundreds of ...
2021Tailored on-chip mid-IR light generation and application for gas spectroscopy
Camille Sophie Brès, Davide Grassani, Eirini Tagkoudi
In this contribution, we present how coherent supercontinuum generation in Si3N4 waveguides enabled by fiber laser pumping can be tailored to cover part of the mid-IR spectrum and the use of such sources in spectroscopy. ...
