This work presents a platform where a 2D heterostructure (WS<jats:sub>2<\/jats:sub>\u2010hBN) is directly integrated into the photonic mode\u2010center of a novel polymer ridge waveguide. Finite\u2010difference time\u2010domain simulations and collection of photoluminescence from the guided mode indicate that this system exhibits significantly improved waveguide\u2010emitter coupling and mode confinement over a previous elastomer platform. This is facilitated by the platform's enhanced refractive\u2010index contrast and a new method for mode\u2010center integration of the coupled TMD. The integration is based on a simple dry\u2010transfer process that is applicable to other 2D materials, and the platform's elastomeric nature is a natural fit to explore strain\u2010tunable hybrid\u2010photonic devices. The demonstrated ability of coupling photoluminescence to a polymer waveguide opens up new possibilities for hybrid\u2010photonic systems in a variety
