    • Chalcogenide microresonators tailored to distinct morphologies by the shaping of glasses on silica tapers 

      Aktaş, O. (OSA - The Optical Society, 2017)
      Production of chalcogenide (As2Se3) microresonators in sphere, loop, and bottle morphologies by the shaping of glasses at appropriate temperatures between cleaved silica tapers is reported. The quality factors exceed QS = ...

    • Designing transmitting CMUT cells for airborne applications 

      Ünlügedik, A.; Taşdelen, A.; Atalar, Abdullah; Köymen, Hayrettin (Institute of Electrical and Electronics Engineers Inc., 2014)
      We report a new mode of airborne operation for capacitive micromachined ultrasonic transducers (CMUT), in which the plate motion spans the entire gap without collapsing and the transducer is driven by a sinusoidal voltage ...

    • Gaziantep'te Sedef Kakma Sanatı ve Sedefkarlık 

      Tercan, Furkan Ataberk; Coşar, Ayşe Ada; Samim, Ecem (Bilkent University, 2019)
      Uzun yıllardır Anadolu insanın el emeğini, el sanatlarına olan ilgisini ve zevkini yansıtan Sedef Kakma sanatı. Türkiye'de ve özellikle Gaziantep ilinde sürdürülmektedir. Bu araştırmada Türkiye'deki tarihçesinden, uygulanan ...

    • Grating based plasmonic band gap cavities 

      Şenlik, S. Seçkin; Kocabaş, Aşkın; Aydınlı, Atilla (Optical Society of American (OSA), 2009-08)
      We report on a comparative study of grating based plasmonic band gap cavities. Numerically, we calculate the quality factors of the cavities based on three types of grating surfaces; uniform, biharmonic and Moiré surfaces. ...

    • Photonic crystal based multi-mode high-qcavity 

      Akosman, Ahmet Emin; Mutlu, Mehmet; Kurt H.; Özbay, Ekmel (IEEE, 2011)
      An optical race-track has been investigated in order to obtain a multi resonant structure with high-Q factors. Photonic crystal based structure provides strong field confinement and scalability in the dimensions of the ...
