Abstract

We propose a novel hybrid modulation format-differential phase shift keying with frequency shift keying labeling for optical label switching. A modulation technique based on a dual-parallel Mach-Zehnder modulator and a label erasing scheme are presented. The tolerance of the new format to intrachannel four-wave mixing at high speeds is studied analytically and through simulations, which show robustness to nonlinear impairments.
