Benefits of Joint Statistics in MLSD-Equalized Transmission
- 2009
-
In: IEEE Photonics Technology Letters. - 1041-1135 .- 1941-0174. ; 21:8, s. 495-497
-
Journal article (peer-reviewed)abstract
- We experimentally investigate and quantify performance improvement, accounting for multiple bit intervals' joint statistics in filtered equalized on-off keying OC-192 fiber-optic links relying on Viterbi-algorithm-based sequence detection. We demonstrate that the penalty associated with narrow filtering can be alleviated for the most part with an appropriate detection approach.

Cancellation of SPM in Self-Homodyne Coherent Systems
- 2009
-
In: Proceedings of European Conference on Optical Communication, ECOC 2009, Vienna, Austria, September 20-24, 2009, paper We8.4.5.
-
Conference paper (peer-reviewed)abstract
- The signal and local oscillator acquire identical nonlinear phase shifts during propagation in a selfhomodynecoherent system. We exploit this to achieve cancellation of the phase distortion caused by self-phasemodulation.

Constellation diagram measurements of induced phase noise in a regenerating parametric amplifier
- 2008
-
In: OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference; San Diego, CA; United States; 24 February 2008 through 28 February 2008. - 9781557528551 ; , s. OML4-
-
Conference paper (peer-reviewed)abstract
- We perform coherent constellation diagram measurements of phase modulated data before and after a saturated parametric amplifier, and find a novel kind of pump-induced phase noise in the amplifier.
