    • Engineering particle trajectories in microfluidic flows using speckle light fields 

      Volpe, G.; Volpe, Giovanni; Gigan, S. (SPIE, 2014)
      Optical tweezers have been widely used in physics, chemistry and biology to manipulate and trap microscopic and nanoscopic objects. Current optical trapping techniques rely on carefully engineered setups to manipulate ...

    • Geometric parametric instability of femtosecond pulses in graded-index multimode fiber 

      Teğin, Ugur; Ortaç, Bülend (Optical Society of America, 2017)
      We numerically and experimentally study the spatio-temporal femtosecond pulse evolution in graded-index multimode fiber at normal dispersion regime. We report the first demonstration of geometric parametric instability ...

    • Roadmap on wavefront shaping and deep imaging in complex media 

      Gigan, Sylvain; Katz, Ori; De Aguiar, Hilton B.; Andresen, Esben Ravn; Aubry, Alexandre; Bertolotti, Jacopo; Bossy, Emmanuel; Bouchet, Dorian; Brake, Joshua; Brasselet, Sophie; Bromberg, Yaron; Cao, Hui; Chaigne, Thomas; Cheng, Zhongtao; Choi, Wonshik; Čižmár, Tomáš; Cui, Meng; Curtis, Vincent R.; Defienne, Hugo; Hofer, Matthias; Horisaki, Ryoichi; Horstmeyer, Roarke; Ji, Na; LaViolette, Aaron K.; Mertz, Jerome; Moser, Christophe; Mosk, Allard P; Pégard, Nicolas C; Piestun, Rafael; Popoff, Sebastien; Phillips, David B.; Psaltis, Demetri; Rahmani, Babak; Rigneault, Hervé; Rotter, Stefan; Tian, Lei; Vellekoop, Ivo M.; Waller, Laura; Wang, Lihong; Weber, Timothy; Xiao, Sheng; Xu, Chris; Yamilov, Alexey; Yang, Changhuei; Yılmaz, Hasan (Institute of Physics, 2022-10)
      The last decade has seen the development of a wide set of tools, such as wavefront shaping, computational or fundamental methods, that allow us to understand and control light propagation in a complex medium, such as ...

    • Spatiotemporal dynamics of self-similar parabolic pulse evolution in multimode fibers 

      Graini, L.; Ortaç, Bülend (Springer New York LLC, 2022-06-05)
      In this paper, we have investigated for the first time, the spatiotemporal dynamics of self-similar parabolic pulse evolution in multimode fibers. Two types of fiber are considered, graded-index and step-index MMFs. For ...

    • Spatiotemporal evolutions of similariton pulses in multimode fibers with Raman amplification 

      Graini, Leila; Ortaç, Bülend (MDPI AG, 2021-09)
      This paper aims to pave the way towards the demonstration of spatiotemporal similariton pulses’ evolution in passive multimode fibers with Raman amplification. We numerically present this issue in graded-index and ...

    • Spatiotemporal instability of femtosecond pulses in graded-index multimode fibers 

      Teǧin, U.; Ortaç, B. (Institute of Electrical and Electronics Engineers Inc., 2017)
      We study the spatiotemporal instability generated by a universal unstable attractor in normal dispersion graded-index multimode fiber for femtosecond pulses for the first time. Experimentally observed spatiotemporal ...
