Abstract
A two-pump parametric architecture is used to demonstrate all-optical packet and bit-level switching at OC-768 data rates. We show that a switched signal can be simultaneously replicated in four parametric bands with arbitrary conjugate states. The conversion efficiencies and extinction ratios are controlled by simple pump-spectral positioning. The use of subrate pump switching is analyzed and demonstrated using arbitrary 40-Gb/s sequences.Keywords
