Valley polarization of exciton-polaritons in monolayer WSe2 in a tunable microcavity

Uproszczony widok
dc.abstract.enMonolayer transition metal dichalcogenides, known for exhibiting strong excitonic resonances, constitute a very interesting and versatile platform for the investigation of light-matter interactions. In this work, we report on a strong coupling regime between excitons in monolayer WSe2 and photons confined in an open, voltage-tunable dielectric microcavity. The tunability of our system allows us to extend the exciton-polariton state over a wide energy range and, in particular, to bring the excitonic component of the lower polariton mode into resonance with other excitonic transitions in monolayer WSe2. We can retain up to 40\% of initial circular polarization of the laser or loose it completely if polariton modes are brought into resonances with low energy excitonic modes.
