- •
Bragg stacks of monolayer MoS2/thin SiO2 films are studied.
- •
These stacks can be engineered as almost perfect broadband absorbers or reflectors.
- •
Purely excitonic Bragg absorbers’ average efficiency can be as high as ~95 %.
- •
Thin TMD films can enhance the metamaterial absorbers’ efficiency and bandwidth.
- •
They can be engineered as reflectors for saturable absorption applications.
