Magnetic-field driven hybridization of heavy- and light-hole Rydberg excitons in GaAs quantum wells
David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate +5
We present a combined theoretical and experimental study of ground and excited Rydberg exciton states in wide GaAs quantum wells exposed to a magnetic field in the Faraday geometry…

Very strong light-matter coupling in patterned GaAs heterostructures
David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate +5
The very strong light-matter coupling regime enables the non-perturbative modification of matter properties via light. Using a patterned GaAs/AlGaAs waveguide with twelve wide quan…

Exciton-Tunable Phase Control and Superstrong Coupling Through Multimode Polariton Engineering in Planar Waveguides
Johannes Bürger, Erika Cortese, Simone Di Muzio +3
Strong light-matter coupling in optical waveguides provides a versatile platform for engineering hybrid polaritonic modes and their dispersion. Here we investigate multimode excito…
