Dense wavelength division multiplexed transmitter based on optical injection locking of strained vertical-cavity surface-emitting lasers Vrije Universiteit Brussel
datacentres employ Vertical-Cavity Surface-Emitting lasers (VCSELs), because of their low cost, small footprint, and capability for large-scale fabrication. Additionally, they can be directly modulated with a low modulation voltage so that power consumption can be further reduced. In order to cope with the increasing demands for higher capacity, dense wavelength division ...
