We measured both transmission and reflection spectra of graphene microribbons on a dielectric substrate. From these spectra, absorption spectra were also derived. The absorption coefficient was found to be largely enhanced when the sample is illuminated from the backside of the dielectric substrate compared to the graphene ribbon side.
