    • Category-selective top-down modulation in the fusiform face area of the human brain during visual search 

      Dar, Salman Ul Hassan; Çukur, Tolga (IEEE, 2017)
      Several regions in the ventral-temporal cortex of the human brain are thought to have representations of specific categories of objects. Furthermore, a distributed network of frontal and parietal brain regions is implicated ...
    • Electrically-reconfigurable integrated photonic switches 

      Fidaner, O.; Demir, Hilmi Volkan; Sabnis V.A.; Harris Jr. J.S.; Miller, D.A.B.; Zheng J.-F. (IEEE, 2004)
      We report remotely electrically reconfigurable photonic switches that intimately integrate waveguide electroabsorption modulators with surface-normal photodiodes, avoiding conventional electronics. These switches exhibit ...
    • High-performance 1.55 μm resonant cavity enhanced photodetector 

      Kimukin, İbrahim; Bıyıklı, Necmi; Özbay, Ekmel (IEEE, 2002)
      A high speed and high efficiency resonant cavity enhanced InGaAs based photodetector was demonstrated. A peak quantum efficiency of 66% was measured along with 31 GHz bandwidth with the device. The photoresponse was found ...
    • High-speed InGaAs based resonant cavity enhanced p-i-n photodiodes 

      Kimukin, İbrahim; Bıyıklı, Necmi; Özbay, Ekmel (IEEE, 2001)
      High-speed InGaAs based resonant cavity enhanced photodiodes were discussed. The responses of the photodiodes was measured under high incident optical powers. Bandwidth-efficiency (BWE) product was used to measure the ...
