Journal ArticleDOI
Physical and logical validation of a network based on all-optical packet switching systems
D. Chiaroni,Bruno Lavigne,Amaury Jourdan,Michel Sotom,L. Hamon,Corinne Chauzat,Jean-Claude Jacquinot,A. Barroso,Thierry Zami,Francois Dorgeuille,Christopher Janz,J.-Y. Emery,Emmanuel Grard,Monique Renaud +13 more
TL;DR: In this article, the authors describe the structure of the packet-switching node and the physical and logical analysis of the network including more than 40 network sections based on 160 Gb/s throughput optical packet switching nodes could operate error free.

Method of limiting coupling losses between monomode optical fibers using a piece of multimode optical fiber
Philippe Darbon,Emmanuel Grard +1 more
TL;DR: In this paper, a method of limiting coupling losses between a monomode optical fiber and an optical system having a mode diameter W'o that is different from Wo is presented, which is characterized by the fact that a piece (4) of multimode fiber is welded onto the end of said monOMode fiber, the weld creating an adiabatic cone in the region where the cores meet.
Patent
Hybrid optical module including an intermediate element
TL;DR: A hybrid optical device includes an intermediate element having good thermal conductivity and a coefficient of thermal expansion similar to that of the active component as discussed by the authors, where an active component is fixed to the intermediate element prior to insertion into the cavity.

High bit rate transmission for NG-PON by direct modulation of DFB laser using discrete multi-tone
C. Milion,T. N. Duong,Naveena Genay,Emmanuel Grard,V. Rodrigues,Benoit Charbonnier,J. Le Masson,Meryem Ouzzif,Philippe Chanclou,A. Gharba +9 more
Abstract: A bit rate as high as 19Gbit/s transmission was experimentally demonstrated for NG-PON without chromatic dispersion compensation by direct modulation of DFB laser using DMT signal combined with adaptive power-bit loading algorithm.
Patent
Optical module with an integrated isolator for coupling a semiconductor laser to a light guide
Emmanuel Grard,Daniel Mousseaux,Beylat Jean-Luc,Auge Jacques,Guerin Jean-Jacques,Eugene Duda +5 more
TL;DR: In this article, a DFB laser is coupled to a monomode line fiber via an isolator constituted by a Faraday rotator crystal and a polarizing fiber, which is welded to a fiber to be coupled.
