  • Konferensbidrag (refereegranskat)abstract
    • We suggest a method for pass/fail testing of PM-QPSK transmitters. The test is based on mask testing with time-resolved EVM and accepts transmitters where individual impairments cause less than 0.5 dB OSNR penalty. The design of the test is performed by computer simulations followed by experimental verification of some key results.

  • DM solitons in long-haul DWDM systems at 40 Gb/s with nonlinear interactions and PMD
  • 2003
  • Ingår i: IEEE Photonics Technology Letters. ; 15:10, s. 1372-4
  • Tidskriftsartikel (refereegranskat)abstract
    • The authors investigate for the first time how polarization mode dispersion and nonlinear interactions affect dense wavelength division multiplexing dispersion management-soliton long-haul transmission using Monte Carlo simulations. They also discuss how the system is affected by an increasing number of wavelength channels

  • Semi-analytic saturation theory of fiber optical parametric amplifiers
  • 2006
  • Ingår i: Journal of Lightwave Technology. ; 24:9, s. 3471-9
  • Tidskriftsartikel (refereegranskat)abstract
    • A semi-analytical theory for the gain saturation of parametric amplifiers is presented. The theory is both simple and intuitive, it is compared with experiments on a parametric amplifier, and a very good agreement is found. Furthermore, using theoretical results, a method to obtain saturation characteristics for parametric amplifiers that have features not easily reproduced by theory is presented. The obtained method finds saturation characteristics in a few steps, providing that the gain studied is above 15 dB, where the approximations upon which our simple expression is based are strictly valid. An exact solution of the gain saturation when the pump power is totally converted is also presented and compared with the simplified expression using previously obtained theoretical results

  • Konferensbidrag (refereegranskat)abstract
    • A novel technique for characterization of power evolution in fiber optic parametric amplifiers based on optical time domain reflectometry is presented. The technique is suitable for analyzing the exponential gain along the amplifying fiber
