Phys. Rev. Lett. 100, 183601 (2008) [4 pages]Ultrabroadband Biphotons Generated via Chirped Quasi-Phase-Matched Optical Parametric Down-ConversionSee Also: Publisher's Note Received 12 December 2007; published 5 May 2008; publisher error corrected 6 May 2008 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 (300-nm bandwidth), we measure the narrowest Hong-Ou-Mandel dip to date, having a full width at half maximum of 7.1 fs. This enables the generation of a high flux of nonoverlapping biphotons with ultrabroad bandwidth, thereby promoting the use of SPDC light in many nonclassical applications. © 2008 The American Physical Society URL:
