2D materials enable quantum well-like performance, while enjoying substrate independence. Together with their unique band-engineering potential, they pose an opportunity for exploring next generation devices. The rationale for heterogeneous integration is material function separation; that is to perform electrooptic switching in light-matter-enhanced or polaritonic material-mode combinations, while reserving the bosonic and weak-interacting character for photonics, ideally Si or SiN platforms for cost and loss competitiveness, respectively. Here we report on the first 2D material (TMD) integration into microring resonators (MRR), and demonstrated tunability to critical coupling regime. This system allows determining the TMD index via a semi-empirical approach, which is challenged by traditional ellipsometry due to the atom-thin TMD. We further discuss MRR-TMD electrooptic modulation contrasting spectrally ON versus OFF exciton tuning. We conclude by discussing optical nanocavity-TMD systems with applications in QED or LED emission, such as radiation and emission-channel engineering.
