Monolayer graphene coupled with subwavelength gratings on top of a gold mirror are experimentally demonstrated with a total absorption of over 99% at a wavelength around 1.5 μm with full‐width half maximum (FWHM) about 20 nm. The experimental results confirm convincingly the theoretical prediction of complete optical absorption for monolayer‐graphene‐based structures in the near‐infrared range.
