Nonlinear near-field spectroscopy of exciton-polaritons in a van der Waals layered waveguide

Valeriy I. Kondratyev, Vanik Shahnazaryan, Mikhail Tyugaev +6

Layered van der Waals materials offer novel opportunities for on-chip waveguiding and development of integrated photonic circuits. In the strong light-matter coupling regime, their…
