OPTICAL COUPLING COMPONENTS FOR SPATIAL MULTIPLEXING IN MULTI-MODE
Roland Ryf1, Cristian A. Bolle1, Johannes von Hoyningen-Huene2; 1Bell Laboratories, Alcatel-Lucent, USA; 2Chair: for Communications, University of Kiel, Germany.
Space-Division Multiplexing for long distance transmission over multi-mode fibers requires mode-multiplexers with high mode selectivity and capable of exciting all fiber modes in a controlled way. We present an architecture for mode multiplexers and its experimental demonstration for a three mode fiber.
 
Th.12.B.2 • 11:45
EXPERIMENTAL INVESTIGATION OF MODAL CROSSTALK USING LCOS-BASED SPATIAL LIGHT MODULATOR FOR MODE CONVERSION
Donato Sperti1,2, Massimiliano Salsi1, Clemens Koebele1, Patrice Tran1, Haik Mardoyan1, Sebastien Bigo1, Aurélien Boutin3, Pierre Sillard4, Gabriel Charlet1; 1Alcatel-Lucent Bell Labs, France; 2Dipartimento di Ingegneria dell'Informazione, Università degli Studi di Parma, Italy; 3Kylia, France; 4Draka, France.
We characterize an LCOS-based mode multiplexer fed with a 100Gb/s PDM-QPSK signal in a transmission experiment over 40km of few-mode fiber. The tolerance of the Q2-factor performance to the crosstalk-induced phase mismatch is quantified.
 
Th.12.B.3 • 12:00
CHANNELIZED FIBER BRAGG GRATINGS FOR INLINE CHROMATIC DISPERSION COMPENSATION OF 40 GB S LINKS ON ITU-50 GRID
Guillaume Brochu1, Michel Morin1, François Trépanier1, Benoit Maheux-Lacroix1, Carl Paquet1, Alka Patel2, Mark Filer2, Christophe Meyer3, Sorin Tibuleac2; 1TeraXion, Canada; 2ADVA Optical Networking, USA; 3ADVA AG Optical Networking, Germany.
Purely phase-sampled fiber Bragg gratings are optimized to produce accurate dispersion compensation for the ITU-50 grid. We report limited penalty by using a cascade of six gratings in a 540 km 40 Gb/s DPSK system.
 
Th.12.B.4 • 12:15
DEMONSTRATION OF END-TO-END INTEROPERABILITY BETWEEN LEGACY 100MBE AND A 40GB/S OPTICAL LABEL SWITCHED NETWORK LAYER
John M. Garcia1, Henrik N. Poulsen1, Daniel J. Blumenthal1; 1Electrical and Computer Engineering, UCSB, USA.
Demonstration of burst mode assembly, detection, and recovery of 100MbE frames as 40Gb/s optical packets enabling scalable interoperability with legacy networks. End-to-end adaptation with <10E-4 packet loss over an 18dB range of received power is demonstrated.
