Here, we present a large area freestanding membrane photonic platform that achieves exceptional enhancement of light matter interactions in monolayer WSe2 via quasi bound states in the continuum. The freestanding architecture effectively suppresses radiative losses and supports high Q optical resonances, leading to enhanced light matter interactions.
