Reconfigurable all-optical header recognition for packet switched networks
C.Tian, Z.Zhang, M.A.F.Roelens, M.Ibsen, P.Petropoulos, D.J.Richardson
We report on an optical packet switching system with a code-reconfigurable switching node. Packet headers are generated and decoded in an all-optical fashion using fiber Bragg gratings (FBGs). The reconfigurable 15-chip, 25 ps/chip quaternary phase coding decoder is based on a uniform FBG, the code of which can be changed dynamically by thermally inducing appropriate phase shifts. We present characterization results on the code-reconfigurable FBG device as well as performance evaluation of the switching system.
