  • Non-linear optical device
    Patent number: 8749875
    Abstract: A non-linear optical device includes a frequency-conversion waveguide and first and second input waveguides. The longitudinal axes of the input waveguides are inclined to that of the frequency-conversion waveguide such a first transverse mode is excited in the latter at the input frequency in operation of the device. The frequency-conversion waveguide supports a second transverse mode at an output frequency of the device, such that the phase velocity of the second transverse mode at the output frequency is substantially equal to that of the first transverse mode at the input frequency, thus providing phase-matching by balancing the effects of chromatic and modal dispersion.
    Type: Grant
    Filed: November 25, 2009
    Date of Patent: June 10, 2014
    Assignee: Qinetiq Limited
    Inventors: David M. Benton, Philip M. Gorman, Paul R. Tapster, David Maurice Taylor, Ewan D. Finlayson
  • Method and apparatus for generating optical beats
    Patent number: 8249119
    Abstract: Apparatus comprising an optical fiber laser having at least two laser cores and means arranged to combine laser output from the at least two laser cores at a first end of the optical fiber laser to produce a combined laser output having one or more beat signals.
