Fractal energy spectrum of a polariton gas in a Fibonacci quasi-periodic potential
Dimitrii Tanese, Evgeni Gurevich, Florent Baboux +7
We report on the study of a polariton gas confined in a quasi-periodic one dimensional cavity, described by a Fibonacci sequence. Imaging the polariton modes both in real and recip…
Direct observation of Dirac cones and a flatband in a honeycomb lattice for polaritons
Thibaut Jacqmin, Iacopo Carusotto, Isabelle Sagnes +7
Two-dimensional lattices of coupled micropillars etched in a planar semiconductor microcavity offer a workbench to engineer the band structure of polaritons. We report experimental…
Giant phase modulation in a Mach-Zehnder exciton-polariton interferometer
C. Sturm, D. Tanese, H. S. Nguyen +8
We report on a new mechanism of giant phase modulation. The phenomenon arises when a dispersed photonic mode (slow light) strongly couples to an excitonic resonance. In such a case…
