    • A1GaN UV photodetectors : from micro to nano 

      Bütün, Serkan (Bilkent University, 2011)
      The absorption edge of AlGaN based alloys can be tuned from deep UV to near UV by changing the composition. This enables the use of the material in various technological applications such as military, environmental ...

    • Coupled plasmonic cavities on moire surfaces 

      Balcı, Sinan; Karabıyık, Mustafa; Kocabaş, Aşkın; Kocabaş, Coşkun; Aydınlı, Atilla (Springer, 2010-08)
      Surface plasmon polariton (SPP) waveguides formed by coupled plasmonic cavities on metallic Moire surfaces have been investigated both experimentally and numerically. The Moire surface, fabricated by interference lithography, ...

    • Grating loaded integrated optical cantilevers 

      Karademir, Ertuğrul (Bilkent University, 2010)
      Cantilever beams are the most important parts of standard scanning probe microscopy. In this work, an integrated optical approach to sense the deflection of a cantilever beam is suggested and realized. A grating coupler ...

    • Plasmonic structures with extraordinary transmission and highly directional beaming properties 

      Cağlayan, H.; Bulu, I.; Özbay, Ekmel (Wiley Periodicals, 2006)
      We studied the grating-coupling phenomena between surface plasmons and electromagnetic waves in the microwave spectrum. We first present the experimental and theoretical results of an enhanced microwave transmission though ...
