    • Air-guided photonic-crystal-fiber pulse-compression delivery of multimegawatt femtosecond laser output for nonlinear-optical imaging and neurosurgery 

      Lanin, A.; Fedotov, I. V.; Sidorov Biryukov, D. S.; Doronina Amitonova, L. V.; Ivashkina, O. I.; Zots, M. A.; Sun, C. K.; Ilday, F. O.; Fedotov, A. B.; Anokhin, K. V.; Zheltikov, A. M. (AIP Publishing LLC, 2012-03-06)
      Large-core hollow photonic- crystal fibers (PCFs) are shown to enable a fiber-format air-guided delivery of ultrashort infrared laser pulses for neurosurgery and nonlinear-optical imaging. With an appropriate dispersion ...

    • A color and shape based algorithm for segmentation of white blood cells in peripheral blood and bone marrow images 

      Arslan, S.; Ozyurek, E.; Gunduz Demir, C. (John Wiley & Sons, Inc., 2014)
      Computer-based imaging systems are becoming important tools for quantitative assessment of peripheral blood and bone marrow samples to help experts diagnose blood disorders such as acute leukemia. These systems generally ...

    • Evidence for Nonradiative Energy Transfer in Graphene-Oxide-Based Hybrid Structures 

      Yeltik, A.; Kucukayan-Dogu, G.; Guzelturk, B.; Fardindoost, S.; Kelestemur, Y.; Demir, Hilmi Volkan (American Chemical Society, 2013-11-13)
      Solution processed graphene variants including graphene oxide (GO) and reduced graphene oxide (RGO) are promising materials for potential optoelectronic applications. To date, efficiency of the excitation energy transfer ...

    • Fabrication of 100 nm pMOSFETS With Hybrid AFW / STM lithography 

      Soh, H. T.; Wilder, K.; Atalar, Abdullah; Quate, C. F. (IEEE, 1997-06)
      Scanning probe lithography (SPL) is an emerging area of research in which the scanning tunneling microscope (STM) or atomic force microscope (AFM) is used to pattern nanometer-scale features. Four factors will dictate ...

    • Hybridization of fano and vibrational resonances in surface-enhanced infrared absorption spectroscopy of streptavidin monolayers on metamaterial substrates 

      Alici, K. B. (2014)
      We present spectral hybridization of organic and inorganic resonant materials and related bio-sensing mechanism. We utilized a bound protein (streptavidin) and a Fano-resonant metasurface to illustrate the concept. The ...

    • Intracavity optical trapping of microscopic particles in a ring-cavity fiber laser 

      Kalantarifard, Fatemeh; Elahi, Parviz; Makey, Ghaith; İlday, F. Ömer; Volpe, Giovanni; Maragò, O. M. (Nature Publishing Group, 2019-06)
      Standard optical tweezers rely on optical forces arising when a focused laser beam interacts with a microscopic particle: scattering forces, pushing the particle along the beam direction, and gradient forces, attracting ...

    • Penetration depth of the scanning acoustic microscope 

      Atalar, Abdullah (IEEE, 1985-03)
      A definition for the penetration depth of the scanning reflection acoustic microscope is given. With this definition it is possible to calculate the penetration depth of a given lens geometry for a given material. The ...

    • Roadmap on wavefront shaping and deep imaging in complex media
