A variety of van der Waals semiconductors feature large oscillator strengths and at the same the flexibility to construct heterostructure and to integrate with a variety of substrates. They allow studies of coherent light-matter interactions that have been difficult to access in traditional materials. We will discuss a few examples, including collective Lamb shift and perfect absorption in a monolayer, cavity-enhanced optical Stark effect, moiré-quantum dot array polaritons with enhanced nonlinearities, and 2D magnet-photonic crystal polaritons that couples atomic and photonic lattice anisotropies. These phenomena open new pathways to novel photonic devices.
