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…
