    • Broadband light generation by noncollinear parametric down-conversion 

      Carrasco, S; Nars, M B; Sergienko, A; Saleh, B E A; Teich, M C; Pérez Torres, Juan; Torner Sabata, Lluís (2006-01)
      Article

      Broadband light generation is demonstrated by noncollinear spontaneous parametric downconversion with a cw pump laser. By use of a suitable noncollinear phase-matching geometry and a tightly focused pump beam, downconverted ...
    • Enhancing the axial resolution of quantum optical coherence tomography by chirped QPM 

      Carrasco, S; Pérez Torres, Juan; Torner Sabata, Lluís; Sergienko, A; Saleh, B E A; Teich, M C (2004-10)
      Article
      Restricted access - publisher's policy
      We show theoretically that a chirped quasi-phase-matching nonlinear crystal structure can significantly enhance the axial resolution in quantum optical coherence tomography by increasing the spectral width of the generated ...
    • Generating ultra-broadband biphotons via chirped QPM down-conversion 

      Teich, M C; Nasr, M B; Carrasco, S; Saleh, B E A; Sergienko, A V; Pérez Torres, Juan; Torner Sabata, Lluís; Hum, D S; Fejer, M M (2008-12)

      Nonlinear Optics: Nonlinear optical response has enhanced our ability to produce coherent light throughout the optical spectral region.
    • Spatial-to-spectral mapping in spontaneous parametric down-conversion 

      Carrasco, S; Pérez Torres, Juan; Torner Sabata, Lluís; Sergienko, A; Saleh, B E A; Teich, M C (2004-10)
      Article
      Restricted access - publisher's policy
      We put forward an approach for manipulating the spectral profile of entangled photon pairs. Such spectral properties are mediated by the geometry of noncollinear spontaneous parametric down-conversion and by selecting the ...
    • Spectral engineering of entangled two-photon states 

      Carrasco, S; Sergienko, A V; Saleh, B E A; Teich, M C; Pérez Torres, Juan; Torner Sabata, Lluís (2006-06)
      Article
      Restricted access - publisher's policy
      We experimentally demonstrate an approach for manipulating the spectral profiles of entangled-photon pairs. The spectral properties are determined by selecting both the appropriate spatial profile of the pump laser radiation ...
    • Ultrabroadband biphotons generated via chirped quasi-phase-matched optical parametric down-conversion 

      Nasr, M B; Carrasco, S; Saleh, B E A; Sergienko, A V; Teich, M C; Pérez Torres, Juan; Torner Sabata, Lluís; Hum, D S; Fejer, M M (2008-05)
      Article
      Restricted access - publisher's policy
      We generate ultrabroadband biphotons via the process of spontaneous parametric down-conversion (SPDC) in quasi-phase-matched nonlinear gratings that have a linearly chirped wave vector. By using these ultrabroadband biphotons ...
