    • openAccess   Diffractive optics for quasi-direct space-to-time pulse shaping 

      Mínguez-Vega, Gladys; Mendoza-Yero, Omel; Lancis, Jesús; Gisbert, Rafael; Andrés, Pedro Optical Society of America (2008)
      The strong chromatic behavior associated with a conventional diffractive lens is fully exploited to propose a novel optical device for pulse shaping in the femtosecond regime. This device consists of two optical elements: ...

    • openAccess   Dispersion requirements in coherent frequency-to-time mapping 

      Torres Company, Víctor; Leaird, Daniel E.; Weiner, Andrew M. Optical Society of America (2011)
      The frequency-to-time mapping technique (also known as the temporal far-field phenomenon) usually requires a significant amount of dispersion to stretch an ultrashort optical pulse so that the intensity profile becomes ...

    • 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 ...

    • closedAccess   Space-Time Analogies in Optics 

      Torres Company, Víctor; Lancis, Jesús; Andrés, Pedro Elsevier (2011)
      The so-called space-timeanalogy constitutes a source of inspiration to understand, engineer, and implement new systems for ultrafast optical signal processing based on concepts borrowed from the well-established field of ...

    • 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 ...
