Quantum dot multi-wavelength lasers for Tbit/s coherent communications and 5G wireless networks -INVITED
We will present the design, growth, fabrication, electronic control and packaging of the InAs/InP quantum dot (QD) multi-wavelength lasers (MWLs) developed by AEP of NRC in Canada. Their key technical specifications include L-I-V curves, optical and RF beating spectra, relative intensity noise (RIN)...
