Quantum-Dot/Dash Semiconductor Multi-Wavelength Lasers
for State-of-the-Art Optical and Wireless Networks
Abstract
The presentation is devoted to the high performance semiconductor quantum dot (Qdot) or dash (Qdash) passively mode-locked based multi-wavelength lasers (ML-MWL) fabricated in NRC Canada. The characterizations from C-band InAs/InP Fabry-Pérot Qdot and Qdash ML-MWLs are demonstrated with different repetition rates (10 to 90 GHz) and laser structures (buried hetero- and surface ridge). The results of phase noise and timing jitter from these lasers are discussed and compared in details by theoretical analysis and experimental measurements. The performances of the lasers are also evaluated in an over ten-Terabit/s aggregate data transmission system and a Millimeter-Wave-over-Fiber fronthaul wireless link at 5G New Radio with high order QAM data formats.
