Applications of Slow Light in Telecommunications

Abstract

Form Approved OMB No. 0704-0188Public reporting burden for the collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Send comments regarding this burden estimate or any other aspect of this collection of information, including suggestions for reducing this burden, to Washington Headquarters Services, Directorate for Information Operations and Reports, 1215 Jefferson Davis Highway, Suite 1204, Arlington VA 22202-4302. Respondents should be aware that notwithstanding any other provision of law, no person shall be subject to a penalty for failing to comply with a collection of information if it does not display a currently valid OMB control number.

Propagation dynamics of controlled cross-talk via interplay betweenχ(1)andχ(3Hsu1, Welch2, Gord3 et al. 2011Phys. Rev. A140100View full textAdd to dashboardCite

“…We have also experimentally demonstrated control of the cross-talk and have shown that the analytical solutions presented yield good quantitative agreement with the experiment. Effective control of cross-talk in the double-ladder system could find many potential applications in optical communication [29] and in quantum information processing as a controllable correlated photon source [30].…”

Achievements in slow and fast light in optical fibres

“…Moreover the performance required by modern telecommunication systems and optical digital processing in terms of delay and bandwidth would require a tremendous pumping power that turns the endeavour into a lost cause [20]. It means that slow-and fast-light delay lines are likely to miss the main target application that motivated the early research efforts, which is the all-optical buffering for the development of future all-optical routers [22]. For such an application, coherent optical storage looks more like a promising approach and recent results show that even SBS can realize this storage function in optical fibres [23].…”

Slow and fast light in optical fibres

“…Although other technologies, such as coupled resonators 6,50 , potentially provide improved storage capabilities, the all-optical and fast delay control that characterizes the fibre-based techniques is not yet possible in such structures. This means that it is difficult for slow-and fast-light delay lines to meet the target application that motivated the early research efforts, that is, the all-optical buffering required for future all-optical routers 51 . For such an application, wavelength conversion associated with a dispersive optical line has proven to be an efficient solution, and the delaying of a full sequence of 1,000 bits at 10 Gbit s -1 has already been demonstrated [52][53][54] .…”
