All optical tunable storage of phase-shift-keyed data packets.

The requirements for higher data rates in optical communication systems lead to the use of more efficient modulation formats. In the networks the all optical synchronization and storage of these signals is still a major challenge in order to enable higher transmittable data rates and reduce the energy consumption. In this contribution we show for the first time, to the best of our knowledge, the tunable storage of phase modulated optical data packets with up to 60 pulse widths. This opens the way to the optical storage of data packets modulated with highly efficient modulation formats.
