    • Critical coupling in plasmonic resonator arrays 

      Balci, S.; Kocabas, C.; Aydınlı, Atilla (Optical Society of America, 2011)
      We report critical coupling of electromagnetic waves to plasmonic cavity arrays fabricated on Moiré surfaces. Dark field plasmon microscopy imaging and polarization dependent spectroscopic reflection measurements reveal ...
    • Observation of gate-tunable coherent perfect absorption of terahertz radiation in graphene 

      Kakenov, N.; Balci, O.; Takan, T.; Ozkan, V. A.; Altan, H.; Kocabas, C. (American Chemical Society, 2016)
      We report experimental observation of electrically tunable coherent perfect absorption (CPA) of terahertz (THz) radiation in graphene. We develop a reflection-type tunable THz cavity formed by a large-area graphene layer, ...
