Second-Harmonic Generation in Suspended AlGaAs Waveguides: A Comparative Study
Autor: Iännis Roland, Marco Ravaro, Stéphan Suffit, Pascal Filloux, Aristide Lemaître, Ivan Favero, Giuseppe Leo
Publikováno v: Micromachines, Vol 11, Iss 2, p 229 (2020)
Due to adjustable modal birefringence, suspended AlGaAs optical waveguides with submicron transverse sections can support phase-matched frequency mixing in the whole material transparency range, even close to the material bandgap, by tuning the width

Harmonic generation with multi-layer dielectric metasurfaces
Autor: Carlo Gigli, Giuseppe Marino, Stéphan Suffit, Giuseppe Leo, Konstantinos Pantzas, Costantino De Angelis, Pascal Filloux, Isabelle Sagnes, Davide Rocco, G. Beaudoin
Publikováno v: Nanophotonics, Vol 10, Iss 7, Pp 1837-1843 (2021)
Metasurfaces have recently gained extensive interest because of their extraordinary optical behavior as artificial material interfaces with ultrahigh compactness. In this framework, dielectric platforms have newly become very promising for nonlinear

Autor: Stéphan Suffit, Emmanuel Lhuillier, Pascal Filloux, Domitille Schanne, Aloyse Degiron
Publikováno v: Applied Physics Letters
Applied Physics Letters, American Institute of Physics, 2021, 119, ⟨10.1063/5.0065486⟩
International audience; It is well known that concentric diffraction gratings are capable of beaming the spontaneous emission of large extended incoherent light sources (e.g. hot radiating surfaces and luminescent materials). Here, we reveal addition

Publikováno v: Physical Review Applied
Physical Review Applied, American Physical Society, 2020, 14 (6), pp.064077. ⟨10.1103/PhysRevApplied.14.064077⟩
International audience; Harnessing the spontaneous emission of incoherent quantum emitters is one of the hallmarks of nano-optics. Yet, an enduring challenge remains—making them emit vector beams, which are complex forms of light associated with fr

Ultrafast gain switching of THz quantum cascade lasers: THz pulse amplification and injection seeding
Autor: J. Maysonnave, Sukhdeep Dhillon, Stefano Barbieri, Pascal Filloux, Julien Madéo, Carlo Sirtori, P. Cavalié, Jérôme Tignon, Xavier Marcadet, Dimitri Oustinov, R. Rungsawang, Nathan Jukam

Laser action normally is initiated by the amplification of spontaneous emission. As spontaneous emission is a random process, the carrier phase of a laser is different each time a laser is turned on. As a consequence, it is not possible to measure th

The QCL carrier phase is set by coherent injection seeding with a THz pulse. This enables the phase-resolved laser emission to be measured in the time-domain and the QCL to be used directly for time-domain-spectroscopy.
