Abstract

In this work we realize an optical resonator incorporating nematic liquid crystal in which photonic cavity modes are in strong light-matter coupling regime with excitons in a 2D organic-inorganic perovskite layer. Using electric field tunability provided by the liquid crystal we can bring our structure to the regime of Rashba-Dresselhaus spin orbit coupling. By a preparation of the orienting polymer layers within the cavity to break inversion symmetry of the liquid crystal layer we were able to engineer polariton energy band structure exhibiting locally non-zero photonic Berry curvature, which can be tuned by an external electric field.
