We report on the integration of monolayer molybdenum disulphide with silicon nitride
microresonators assembled by visco-elastic layer transfer techniques. Evanescent coupling
from the resonator mode to the monolayer is confirmed through measurements of cavity
transmission. The absorption of the monolayer semiconductor flakes in this geometry is
determined to be 850 dB/cm, which is larger than that of graphene and black phosphorus
with the same thickness. This technique can be applied to diverse monolayer …

Monolayers of transition metal dichalcogenides exhibit interesting low-dimensional opto-
electronic phenomena and large optical interactions. Harnessing these features for
modulating light requires interfacing these monolayer semiconductors with photonic
devices. Here, we show the integration of monolayer molybdenum disulphide (MoS 2) with
silicon nitride ring microresonators using a visco-elastic layer transfer. Cavity transmission is
used to measure the coupling of the monolayer evanescently coupled to the ring resonator …
