  • The development of efficient integrated photonic circuits is fundamental for ongoing research in information processing and computer science. The greatest challenge in strong light-matter regime facing photonic systems is achieving strong nonlinearities, which are exploitable in strongly coupled systems, leading to the formation of exciton-polaritons. In this context, the use of hybrid organic-inorganic perovskites offers a promising alternative, exhibiting robust interactions at Room Temperature (RT). However, the development of perovskite-based integrated devices requires both the ability to achieve long in-plane propagation, and the development of alternative fabrication approaches tailored to perovskite materials, designed to preserve their optical properties and prevent degradation. Herein, we present the realization of a proof-of-concept all-optical switch using propagating polaritons confined in Total Internal Reflection (TIR), which ensures long in-plane propagation and limited optical losses. We realized an efficient injection/extraction of the TIR-confined waveguide polariton modes by employing gold grating couplers prepatterned on the substrate.
