Transition metal dichalcogenides (TMDCs) exhibit extraordinary optical, electrical, and mechanical properties that can be easily tailored for novel integrated photonic applications. Different TMDCs can be combined to form novel nanostructures with highly interesting complex dynamics. Here, we report on the simulation and fabrication of a WS2-nanobeam cavity with a MoSe2 monolayer (ML) as active material. Utilizing a FEM eigenfrequency solver, cavity simulations are performed on a 3D stripe of WS2 with a finite periodic air hole arrangement. The calculated eigenmodes exhibit high Q-factors and tight mode confinement with mode volumes near the fundamental diffraction limit after parameter optimization. The final parameter set is employed in the fabrication process of WS2-nanobeam cavities with a MoSe2 ML embedded in them. This work paves further the way toward the realization of novel nanolaser devices consisting purely of TMDC materials.
