    • Novel optical antennas inspired by metamaterial architectures 

      Kılıç, Veli Tayfun (Bilkent University, 2011)
      The spatial resolution of conventional optical systems is commonly constrained by the diffraction limit. This is a fundamental problem important for various high-tech applications including density limitation in data ...
    • Novel volumetric plasmonic resonator architectures for enhanced absorption in thin-film organic solar cells 

      Sefünç, Mustafa Akın (Bilkent University, 2010)
      There has been a growing interest in decreasing the cost and/or increasing the efficiency of clean renewable energy resources including those of photovoltaic approaches for conversion of sunlight into electricity. Today, ...
    • A plasmonically enhanced pixel structure for uncooled microbolometer detectors 

      Erturk O.; Battal, E.; Kucuk, S.E.; Okyay, A., K.; Akin, T. (2013)
      This paper introduces a method of broadband absorption enhancement that can be integrated with the conventional suspended microbolometer process with no significant additional cost. The premise of this study is that electric ...
    • Semiconductor-less photovoltaic device 

      Atar F.B.; Battal, E.; Aygun L.E.; Daglar, B.; Bayindir, M.; Okyay, A., K. (2013)
      We demonstrate a novel semiconductor-less photovoltaic device and investigate the plasmonic effects on this device structure. The device is made of metal and dielectric layers and the operation is based on hot carrier ...
