    • Ablation-cooled material removal at high speed with femtosecond pulse bursts 

      Kerse, C.; Kalaycioglu H.; Elahi P.; Akcaalan Ö.; Yavaş, S.; Aşik, M.D.; Kesim, D.K.; Yavuz, K.; Çetin, B.; Ilday F.Ö. (Optical Society of America (OSA), 2015)
      We report exploitation of ablation cooling, a concept well-known in rocket design, to remove materials, including metals, silicon, hard and soft tissue. Exciting possibilities include ablation using sub-microjoule pulses ...
    • Fabrication and characterization of high speed resonant cavity enhanced Schottky photodiodes 

      Islam, M Saiful (Bilkent University, 1996)
      High speed, high external quantum efficiency and narrow spectral linewidth make resonant cavity enhanced (RC E) Schottky photodetector a good candidate for telecommunication applications. In this thesis, we present our ...
    • High-speed, thermal damage-free ablation of brain tissue with femtosecond pulse bursts 

      Kerse C.; Yavas S.; Kalaycioglu H.; Asik M.D.; Akcaalan O.; Ilday F.O. (Institute of Electrical and Electronics Engineers Inc., 2016)
      We report a novel ultrafast burst mode fiber laser system and results on ablation of rat brain tissue at rates approaching an order of magnitude improvement over previous reports, with no discernible thermal damage. © 2015 IEEE.
    • InGaAs-based high-performance p-i-n photodiodes 

      Kimukin, I.; Biyikli, N.; Butun, B.; Aytur, O.; Ünlü, S. M.; Ozbay, E. (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 ...
    • Long wavelength GaAs based hot electron photoemission detectors 

      Kimukin, İbrahim (Bilkent University, 1999)
      The increasing rate of telecommunication alters both science and technology, and demands high performance components. Photo detectors are essential components of optoelectronic integrated circuits and fiber optic ...
