Abstract
This paper proposes a technique to realize quasi-hitless defragmentation in elastic optical networks. The technique exploits fast tunable lasers in the transponders and a rapid TX wavelength tracking scheme at the RX based on an athermal AWG and a PD-array. The propose scheme can potentially achieve defragmentation operation with a service disruption time below 400ns.
