Chair: Magnus Karlsson; Chalmers University of Technology (CTH), Sweden
 
Th.12.LeCervin.1 • 11:15
MEASURED PHASE AND GROUP BIREFRINGENCE IN ELLIPTICAL CORE FIBERS WITH UNPARALLELED SYSTEMATICALLY VARIED ELLIPTICITIES
Tommy Geisler1, Søren Herstrøm1; 1OFS Fitel Denmark ApS, Denmark.
This paper presents the first systematic phase and group birefringence measurement of elliptical core fibers covering an unprecedented ellipticity range from 0-0.9. Results are compared with simulations and the impact of core area is discussed.

NON-INTRUSIVE IN-SERVICE PMD MEASUREMENTS: A NOVEL APPROACH BASED ON COHERENT DETECTION
Vincent Lecoeuche1, Fabien Sauron1, Pascal Roa1, Alexandre Cebollada1, Benjamin Cuenot1, André Champavère1, Olivier Masselin1, Fred Heismann2; 1CommTest, JDSU, France; 2Optical Networks Research Lab, JDSU, USA.
We describe a novel method for in-service Polarization Mode Dispersion measurements and compare its accuracy with the Jones matrix eigen-analysis method. A relative accuracy of 4% is reported over a 1-50ps mean DGD range.

EXPERIMENTAL EVIDENCES OF INDEPENDENCE BETWEEN BIREFRINGENCE MODULUS AND SPIN RATE IN PERIODICALLY SPUN FIBERS
Luca Palmieri1, Tommy Geisler2, Andrea Galtarossa1; 1Dept. of Information Engineering, University of Padova, Italy; 2OFS Fitel Denmark ApS, Denmark.
We report on polarization sensitive characterization of a set of various fibers, showing that in periodically spun fibers there is no evident correlation between the local birefringence strength and the applied spin rate.
 
Th.12.LeCervin.4 • 12:00
ALL-OPTICAL SIMULTANEOUS POLARIZATION ATTRACTION AND INTENSITY REGENERATION OF A 40-GBIT/S RZ SIGNAL
Philippe Morin1, Julien Fatome1, Christophe Finot1, Stephane Pitois1, Guy Millot1; 1ICB, Laboratoire Interdisciplinaire Carnot de Bourgogne, France.
We experimentally demonstrate that is possible, using a unique segment of fiber, to simultaneously, instantaneously and all-optically manipulate and regenerate both the state of polarization and intensity profile of a 40-Gbit/s Return-to-Zero telecommunication signal.
 
Th.12.LeCervin.5 • 12:15
A NOVEL FIGURE OF MERIT TO COMPARE FIBERS IN COHERENT DETECTION SYSTEMS WITH UNCOMPENSATED LINKS
Andrea Carena1, Vittorio Curri1, Gabriella Bosco1, Roberto Cigliutti1, Enrico Torrengo1, Pierluigi Poggiolini1, Antonino Nespola2, Dario Zeolla2, Fabrizio Forghieri3; 1Dipartimento di Elettronica, Politecnico di Torino, Italy; 2Istituto Superiore Mario Boella, Italy; 3Cisco Photonics Italy, Italy.
We introduce an improved Figure of Merit for comparing different uncompensated fiber links for coherent transmission. The role of fiber dispersion in enhancing system performance is shown and verified by simulations and experiments.
 
Th.12.LeCervin.6 • 12:30
LOW DISTORTION 6-COPY MULTICASTING OF ANALOG SIGNAL USING SELF-SEEDED PARAMETRIC MIXER
Andreas O. J. Wiberg1, Evgeny Myslivets1, Camille-Sophie Bres1, Stojan Radic1; 1Electrical and Computer Engineering, University of California San Diego, USA.
We present the highest performing multicasting of six copies generated in a self-seeded parametric mixer using distortion free SBS suppression. The multicasting operation results in high signal-to-noise and -distortion-ratio wavelength copies compatible for analog processing.
 
Th.12.LeCervin.7 • 12:45
EFFECT OF RAYLEIGH-SCATTERING DISTRIBUTED FEEDBACK IN MULTI-WAVELENGTH AND TUNABLE RAMAN FIBRE LASERS
Sergei Babin1, Atalla El-Taher2, Paul Harper2, Evgenii Poduvilov1, Dmitryi Churkin1, Sergei K. Turitsyn2; 1Institute of Automation and Electrometry, SB RAS,, Russian Federation; 2Photonics Research Group, Aston University, United Kingdom.
We have demonstrated that a random distributed feedback based on the Rayleigh scattering provides very flat power-versus-wavelength characteristics both in tunable and multi-wavelength ultra-long fibre lasers.
