    • 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 1.55 μm operation of low-temperature-grown GaAs-based resonant-cavity-enhanced p-i-n photodiodes 

      Butun, B.; Bıyıklı, Necmi; Kimukin, I.; Aytur, O.; Özbay, Ekmel; Postigo, P. A.; Silveira, J. P.; Alija, A. R. (American Institute of Physics, 2004)
      The 1.55 μm high-speed operation of GaAs-based p-i-n photodiodes was demonstrated and their design, growth and fabrication were discussed. A resonant-cavity-detector structure was used to selectively enhance the photoresponse ...

    • 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 ...

    • High-speed widely-tunable >90% quantum-efficiency resonant cavity enhanced p-i-n photodiodes 

      Bıyıklı, Necmi; Kimukin, İbrahim; Aytür, Orhan; Gökkavas, M.; Ulu, G.; Mirin, R.; Christensen, D. H.; Ünlü, M. S.; Özbay, Ekmel (IEEE, 1998)
      Widely-tunable high-speed resonant cavity enhanced p-i-n photodiodes were designed, fabricated and tested for operation around 820 nm. The structure was grown by solid-source MBE on GaAs substrates and features high-reflectivity ...

    • InGaAs-based high-performance p-i-n photodiodes 

      Kimukin, I.; Bıyıklı, Necmi; Butun, B.; Aytur, O.; Ünlü, S. M.; Özbay, Ekmel (IEEE, 2002-03)
      In this letter, we have designed, fabricated, and characterized high-speed and high efficiency InGaAs-based p-i-n photodetectors with a resonant cavity enhanced structure. The devices were fabricated by a microwave-compatible ...

    • Ultrafast and highly efficient resonant cavity enhanced photodiodes 

      Özbay, Ekmel; Kimukin, İbrahim; Bıyıklı, Necmi (SPIE, 2003-09)
      In this talk, we will review our research efforts on resonant cavity enhanced (RCE) high-speed high-efficiency photodiodes (PDs) operating in the 1st and 3rd optical communication windows. Using a microwave compatible ...
