Bias-resolved comb-formation regimes in a simple two-section quantum-dot mode-locked laser for isolator-free, terabit-scale O-band interconnects
Ying Shi, William He, Xiangpeng Ou +4
Practical O-band quantum-dot (QD) mode-locked comb sources must combine wide flat-top bandwidth, low radio-frequency (RF) timing noise, error-correctable bare-line modulation, and…

Mode Control and Dynamic Population Gratings in Quantum-Dot Lasers
Xiangpeng Ou, Artem Prokoshin, Hongyan Yu +5
Single-mode operation is essential for integrated semiconductor lasers, yet most solutions rely on regrowth, etched gratings, or other complex fabrication steps that limit scalabil…
