    • openAccess   Fresnel phase retrieval method using an annular lens array on an SLM 

      Loriot, Vincent; Mendoza-Yero, Omel; Pérez Vizcaíno, Jorge; Mínguez-Vega, Gladys; De Nalda, R.; Bañares, Luis; Lancis, Jesús Springer (2014-10)
      Wavefront aberrations play a major role when focusing an ultrashort laser pulse to a high-quality focal spot. Here, we report a novel method to measure and correct wavefront aberrations of a 30-fs pulsed laser beam. The ...

    • openAccess   High-visibility interference fringes with femtosecond laser radiation 

      Martinez Cuenca, Raul; Martínez-León, Lluís; Lancis, Jesús; Mínguez-Vega, Gladys; Mendoza-Yero, Omel; Tajahuerce, Enrique; Clemente Pesudo, Pedro Javier; Andrés, Pedro Optical Society of America (2009)
      We propose and experimentally demonstrate an interferometer for femtosecond pulses with spectral bandwidth about 100 nm. The scheme is based on a Michelson interferometer with a dispersion compensating module. A diffractive ...

    • openAccess   Multitap microwave photonic filters with programmable phase response via optical frequency comb shaping 

      Song, Minhyup; Torres Company, Víctor; Metcalf, Andrew J.; Weiner, Andrew M. Optical Society of America (2012)
      We present a programmable multitap microwave photonic filter with an arbitrary phase response operating over a broad bandwidth. Complex coefficient taps are achieved by optical line-by-line pulse shaping on a 10 GHz flat ...

    • openAccess   Programmable quasi-direct space-to-time pulse shaper with active wavefront correction 

      Mendoza-Yero, Omel; Loriot, Vincent; Pérez Vizcaíno, Jorge; Mínguez-Vega, Gladys; Lancis, Jesús; De Nalda, Rebeca; Bañares, Luis Optical Society of America (2012)
      We experimentally demonstrate an extremely compact and programmable pulse shaper composed of a single phase mask encoded into a spatial light modulator. Its principle of operation is similar to the previously theoretically ...

    • openAccess   Simultaneous broadband microwave downconversion and programmable complex filtering by optical frequency comb shaping 

      Torres Company, Víctor; Leaird, Daniel E.; Weiner, Andrew M. Optical Society of America (2012)
      High-repetition-rate optical frequency combs can act as broadband photonic mixers and downconvert a microwave signal to an intermediate frequency (IF) band so that it becomes accessible with high-speed electronics. In this ...

    • openAccess   Synthesis of fractal light pulses by quasi-direct space-to-time pulse shaping 

      Mendoza-Yero, Omel; Alonso, Benjamín; Mínguez-Vega, Gladys; Sola, Íñigo Juan; Lancis, Jesús; Monsoriu, Juan A. Optical Society of America (2012)
      We demonstrated a simple diffractive method to map the self-similar structure shown in squared radial coordinate of any set of circularly symmetric fractal plates into self-similar light pulses in the corresponding temporal ...
