Abstract Multimode behavior plays a key role in a wide range of nonlinear optical phenomena. Multiple exciton-polariton modes can attain macroscopic population as observed in time-integrated measurements. Recent theory work has shown that, rather tha

Artificial periodic lattices of microcavities filled with optically active materials can serve as a platform to explore a range of physical phenomena. Here, the authors prepare and analyse 2D Lieb lattices made from a tunable cavity array with an org

Abstract For guiding light on a chip, it has been pivotal to use materials and process flows that allow low absorption and scattering. Based on subwavelength gratings, here, we show that it is possible to create broadband, multimode waveguides with v

Microcavities with embedded optically active materials allow to create exciton–polariton condensates in the strong light–matter interaction regime. These condensates exhibit quantum fluid properties up to room temperature, and, when crystal-like

We use silicon sub-wavelength high index contrast gratings to create on-chip integrated multimode waveguides. We succeeded in guiding visible light at 600 nm wavelength with losses down to 6 dB/cm despite strong material absorption.
