## Description

- description: We report the design and fabrication of a vertical structure using
    a distributed Bragg reflector (DBR) and spacer layer to achieve optimized optical
    absorption enhancement for a stack of monolayer WS2 and MoS2, namely a 10-fold
    increase of absorption over a 100 nm spectral range. Our research indicates that
    we can approach over 50% absorption by finely tuning the thickness of the spacer
    layer. Our theoretical model shows that the dependence of the absorption coefficient
    on the spacer thickness can be understood as a solution of a non-Hermitian Schrodinger
    equation. These results advance the development of broadband optical devices using
    two-dimensional excitonic materials.
