Ultra-Fast Tunable Laser Enabling 4 ns Coherent Slot Switching Beyond 100 Gbit/s

Abstract

We demonstrate ultra-fast wavelength switching of a narrow linewidth tunable laser. It enables coherent slot switching with a waiting time comprising laser switching, stabilization, channel estimation and data recovery under 4 ns (resp. 30 ns) for 32 Gbaud dual polarization QPSK (resp. 16QAM).
