Advanced Concepts and Devices forOptical Communications and
" The usual (AGWN channel) relation between SNRand BER is broken by:! Non linear propagation! In line 3R regeneration
" Optical channels are not Gaussian and areasymmetric! Specific FEC! Decision threshold optimization
" Constant envelope modulation format arepromising
" Axes of research :! Phase and amplitude quantum noise modeling! Statistical characterization of the optical channel! Development of FEC adapted to typical optical error! Joint optimization of FEC and modulation formats! Optimization of the “In line/Electronics/Optics”
decision partitioning
ANR National Project : ECOFRAME

Advanced Digital Optical Communication 2/2
" Chi!Statistical model
" Gaussian decision threshold is NOT optimal
" Unbalance between errors on symbols "1" and"0”
" Euclidian norm is no longer valid for codingschemes
" Constraint codes are good candidates for thisnew model

“All Optical” Clock Recovery 1/4
" Self-Pulsation (SP) of Laser Diode (LD)! Beating between optical modes
! Non-linear regime# Saturable absorption in an unpumped region
# Gain non linearity
" Applications for SP lasers! All-optical clock recovery
" RF beating of phase correlated optical signals! Injection locking of different SC lasers
! Single modulated master SC laser
! Slave lasers locked on different modulation side-band
