Tensor-driven geometric phase in nonlinear AlGaAs metasurfaces
Giorgio Guercio, Andrea Gerini, Kristina Frizyuk +5
Dielectric metasurfaces provide a unique platform for efficient harmonic generation and optical wavefront manipulation at the nanoscale. While several approaches are available for…
Dispersion engineered AlGaAs-on-insulator nanophotonics by distributed feedback
Francesco Rinaldo Talenti, Luca Lovisolo, Zijun Xiao +9
Technological advances in the fabrication of nanophotonic circuits have driven the scientific community to increasingly focus on the precise tailoring of their key optical properti…
All-optical polarization control and routing by nonlinear interferometry at the nanoscale
Yigong Luan, Attilio Zilli, Agostino Di Francescantonio +7
Optical metasurfaces are rapidly establishing as key-enabling platforms for nanophotonics applications. Along with the ability of taming light in subwavelength thicknesses, they ca…
Efficient optical coupling to gallium arsenide nano-waveguides and resonators with etched conical fibers
Samuel Pautrel, Florent Malabat, Louis Waquier +4
We explore new methods for coupling light to on-chip gallium arsenide nanophotonic structures using etched conical optical fibers. With a single-sided conical fiber taper, we demon…
Whispering gallery quantum well exciton polaritons in an Indium Gallium Arsenide microdisk cavity
Romain de Oliveira, Martin Colombano, Florent Malabat +3
Despite appealing high-symmetry properties that enable high quality factor and strong confinement, whispering gallery modes of spherical and circular resonators have been absent fr…
Light-mediated cascaded locking of multiple nano-optomechanical oscillators
Eduardo Gil-Santos, Matthieu Labousse, Christophe Baker +7
Collective phenomena emerging from non-linear interactions between multiple oscillators, such as synchronization and frequency locking, find applications in a wide variety of field…
Monolithic AlGaAs second-harmonic nanoantennas
V. F. Gili, L. Carletti, A. Locatelli +9
We demonstrate monolithic aluminum gallium arsenide (AlGaAs) optical anoantennas. Using a selective oxidation technique, we fabricate such epitaxial semiconductor nanoparticles on…
Miniature GaAs disk resonators probed by a looped fiber taper for optomechanics applications
L. Ding, P. Senellart, A. Lemaitre +3
GaAs disk resonators (typical disk size 5 \mum * 200 nm in our work) are good candidates for boosting optomechanical coupling thanks to their ability to confine both optical and me…
Damping of optomechanical disks resonators vibrating in air
D. Parrain, C. Baker, T. Verdier +5
We report on miniature GaAs disk optomechanical resonators vibrating in air in the radiofrequency range. The flexural modes of the disks are studied by scanning electron microscopy…
Critical optical coupling between a GaAs disk and a nanowaveguide suspended on the chip
C. Baker, C. Belacel, A. Andronico +6
We report on an integrated GaAs disk/waveguide system. A millimeter-long waveguide is suspended and tapered on the chip over a length of 25 μm to evanescently couple to high Q opti…
