title = "Tunability of optical absorption in a heterostructure with an embedded graphene sliver",
abstract = "A key design component of optical instruments employed in diverse roles such as detectors, optical resonators, and thermal-imaging cameras is enhancement of the optical absorption. The efficiency of absorption in conventional thin metallic films can be further improved by replacing them with graphene detectors. While graphene exhibits a high absorption and quantum efficiency for light-matter interactions [1-2], the optical absorption of single-atom layer graphene is poor to be an efficient photo-detector [3]. Its adaptability for various frequency ranges is also limited by a flat absorption spectrum in the visible to near-infrared region. In this work, using a transfer matrix approach [4], we present methods to enhance the optical absorption in a graphene sliver sandwiched between dielectric media via adjustments to the thickness of the dielectrics, incident angle and wavelength of the EM wave, and chemical potential of the graphene layer. The model equations are presented in Table I.",
