The optical absorption of monolayer MoS{sub 2} on top of one-dimensional photonic crystal (1DPC) or metal films with spacer layers is theoretically investigated by extracting the permittivity of monolayer MoS{sub 2} from existing experimental results [K. F. Mak et al., Phys. Rev. Lett. 105, 136805 (2010)]. The absorption of graphene with 1DPC across a broad spectral range is substantially enhanced because of the photonic localization at the optical micro-cavity on top of the 1DPC or metal films. The absorption of monolayer MoS{sub 2} can be tuned by varying either the distance between the monolayer MoS{sub 2} and the back reflector or the thickness of the cover layers.
