Graphene/MoS2 Heterostructure Photodetector Integrated with Silicon Nitride Micro-Ring Resonators at Visible Wavelengths

In this work, we fabricate a graphene/MoS
₂
heterostructure photodetector integrated on silicon nitride micro-ring waveguide resonators. Taking advantage of resonant mode coupling with two-dimensional materials, our device obtains a photoresponsivity of 0.58 A/W.
