Atomically thin 2D materials provide a wide range of basic building blocks with unique properties, making them ideal for heterogeneous integration mature chip platform. An understanding the role excitons in transition metal dichalcogenides Silicon photonic platform is prerequisite advances optical communication technology, signal processing, and possibly computing. Here we demonstrate passive tunable coupling by integrating few layers MoTe2 on micro-ring resonator. We find TMD-to-rings circumference coverage length ratio to place ring into critical be about 10% as determined from variation spectral resonance visibility loss function TMD coverage. Using this heterostructure, further semi-empirical method determine index an unknown material (nMoTe2 4.36+.011i) near telecommunication-relevant wavelength.
