Very strong light-matter coupling in patterned GaAs heterostructures

David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate, Jesper Levinsen et autres

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 quantum wells, we demonstrate hybridization of heavy- and light-hole excitons within a single polariton state and show that, at …

Magnetic-field driven hybridization of heavy- and light-hole Rydberg excitons in GaAs quantum wells

David de la Fuente Pico, Johannes Bürger, Antonio Gianfrate, Jesper Levinsen et autres

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. We employ a multiband exciton model based on the Luttinger Hamiltonian, which captures …

Exciton-Tunable Phase Control and Superstrong Coupling Through Multimode Polariton Engineering in Planar Waveguides

Johannes Bürger, Erika Cortese, Simone Di Muzio, D. Sanvitto et autres

Strong light-matter coupling in optical waveguides provides a versatile platform for engineering hybrid polaritonic modes and their dispersion. Here we investigate multimode exciton-photon coupling in visible semiconductor waveguides supporting several transverse electric modes. Using rigorous coupled-wave analysis combined with a coupled-oscillator model, …

Impact of coordinate frames on mode formation in twisted waveguides

Johannes Bürger, Adrià Canós Valero, Thomas M Weiss, Stefan Alexander Maier et autres

Off-axis twisted waveguides possess unique optical properties such as circular and orbital angular momentum (OAM) birefringence, setting them apart from their straight counterparts. Analyzing mode formation in such helical waveguides relies on the use of specific coordinate frames that follow the twist …
