FRET distance dependence from upconverting nanoparticles to quantum dots
Sonia Melle, Oscar G. Calderon, Marco Laurenti +6
Förster resonant energy transfer (FRET) with upconverting nanoparticles (UCNPs) as donors and quantum dots (QDs) as acceptors has been regarded as a promising tool for biosensing a…
Boosting terahertz generation in laser-field ionized gases using a sawtooth wave shape
P. González de Alaiza Martínez, I. Babushkin, L. Bergé +6
Broadband ultrashort terahertz (THz) pulses can be produced using plasma generation in a noble gas ionized by femtosecond two-color pulses. Here we demonstrate that, by using multi…
Spectral self-action of THz emission from ionizing two-color laser pulses in gases
Eduardo Cabrera-Granado, Yxing Chen, Ihar Babushkin +2
The spectrum of terahertz (THz) emission in gases via ionizing two-color femtosecond pulses is analyzed by means of a semi-analytic model and finite-difference-time-domain simulati…
Slow light in molecular aggregates nanofilms
E. Cabrera-Granado, E. Díaz, Oscar G. Calderón
We study slow light performance of molecular aggregates arranged in nanofilms by means of coherent population oscillations (CPO). The molecular cooperative behavior inside the aggr…
Tailoring THz radiation by controlling tunnel photoionization events in gases
I. Babushkin, S. Skupin, A. Husakou +4
Applications ranging from nonlinear terahertz spectroscopy to remote sensing require broadband and intense THz radiation which can be generated by focusing two-color laser pulses i…
Directionality of THz emission from photoinduced gas plasmas
Christian Köhler, Eduardo Cabrera-Granado, Ihar Babushkin +3
Forward and backward THz emission by ionizing two-color laser pulses in gas is investigated by means of a simple semi-analytical model based on Jefimenko's equation and rigorous Ma…
Competition between the Modulation Instability and Stimulated Brillouin Scattering in a Broadband Slow Light Device
Yunhui Zhu, E. Cabrera-Granado, Oscar G. Calderon +4
We observe competition between the modulation instability (MI) and stimulated Brillouin scattering (SBS) in a 9.2-GHz broadband SBS slow light device, in which a standard 20-km-lon…
