    • Beam focusing in reflections from flat subwavelength diffraction gratings 

      Cheng, Yu Chieh; Redondo, Javier; Staliunas, Kestutis (2014-03-10)
      Article
      Accés obert
      We predict that narrow beams, reflecting from flat subwavelength diffraction gratings, can focus. The effect is shown for the beams of electromagnetic radiation; however, it should be observable for beams of waves of ...

    • Beam shaping in spatially modulated broad-area semiconductor amplifiers 

      Herrero Simon, Ramon; Botey Cumella, Muriel; Radziunas, Mindaugas; Staliunas, Kestutis (2012-12-15)
      Article
      Accés obert
      We propose and analyze a beam-shaping mechanism that in broad-area semiconductor amplifiers occurs due to spatial pump modulation on a micrometer scale. The study, performed under realistic parameters and conditions, ...
