Laser-guided lightning
Aurélien Houard, Pierre Walch, Thomas Produit +25
Electric currents circulating between charged clouds and the earth surface during lightning discharges are responsible for considerable damages and casualties. It is therefore impo…
HV discharges triggered by dual- and triple-frequency laser filaments
Thomas Produit, Pierre Walch, Guillaume Schimmel +10
We study the use of frequency upconversion schemes of near-IR picosecond laser pulses and compare their ability to guide and trigger electric discharges through filamentation in ai…
Highly efficient 4 micron light generation through fs-fiber laser driven supercontinuum in SiN waveguides
Davide Grassani, Eirini Tagkoudi, Hairun Guo +3
Directly accessing the middle infrared, the molecular functional group spectral region, via supercontinuum generation processes based on turn-key fiber lasers offers the undeniable…
Double inverse nanotapers for efficient light coupling to integrated photonic devices
Junqiu Liu, Arslan S. Raja, Martin H. P. Pfeiffer +5
Efficient light coupling into integrated photonic devices is of key importance to a wide variety of applications. "Inverse nanotapers" are widely used, in which the waveguide width…
Mid-infrared frequency comb generation with silicon nitride nano-photonic waveguides
Clemens Herkommer, Adrien Billat, Hairun Guo +5
Mid-infrared optical frequency combs are of significant interest for molecular spectroscopy due to the large absorption of molecular vibrational modes on one hand, and the ability…
Octave-spanning dissipative Kerr soliton frequency combs in microresonators
Martin H. P. Pfeiffer, Clemens Herkommer, Junqiu Liu +5
Octave-spanning, self-referenced frequency combs are applied in diverse fields ranging from precision metrology to astrophysical spectrometer calibration. In the past decade, Kerr…
