    • Dynamic nonlinear optical processes in some oxygen-octahedra ferroelectrics: first principle calculations 

      Simsek S.; Koc, H.; Palaz S.; Oltulu, O.; Mamedov, A. M.; Özbay, Ekmel (Taylor & Francis Inc., 2015)
      The nonlinear optical properties and electro-optic effects of some oxygen-octahedra ferroelectrics are studied by the density functional theory (DFT) in the local density approximation (LDA) expressions based on first ...
    • Engineering nonlinear response of nanomaterials using Fano resonances 

      Turkpence, D.; Akguc G.B.; Bek, A.; Tasgin, M.E. (Institute of Physics Publishing, 2014)
      We show that nonlinear optical processes of nanoparticles can be controlled by the presence of interactions with a molecule or a quantum dot. By choosing the appropriate level spacing for the quantum emitter, one can either ...
    • Filtering in fractional Fourier domains and their relation to chirp transforms 

      Özaktaş, Haldun M.; Barshan, Billur; Onural, Levent; Mendlovic, D. (IEEE, 1994-04)
      Fractional Fourier transforms, which are related to chirp and wavelet transforms, lead to the notion of fractional Fourier domains. The concept of filtering of signals in fractional domains is developed, revealing that ...
    • Wafer bonded capacitive micromachined underwater transducers 

      Olcum, Selim; Oǧuz, Kaan; Şenlik, Muhammed N.; Yamaner F. Y.; Bozkurt, A.; Atalar, Abdullah; Köymen, Hayrettin (IEEE, 2009-09)
      In this work we have designed, fabricated and tested CMUTs as underwater transducers. Single CMUT membranes with three different radii and 380 microns of thickness are fabricated for the demonstration of an underwater CMUT ...
