While being cost effective and robust to external optical feedback, conventional Fabry–Perot (FP) semiconductor laser diodes cannot be used for fiber-optic communication systems beyond 1 Gb/s with span requirement over several kilometers due to the mode partition noise (MPN) caused by their multimode operation nature. In order to reduce the MPN-induced power penalty, we have proposed a narrow spectral...
The explosive growth of Internet traffic leads to increasing demands for communication bandwidth. Meanwhile, the size, power and cost requirements of the optical links are also imposed. It has been recognized that the spectral width and the mode partition noise (MPN) of the multi-mode lasing source are major limiting factors in high-speed, yet cost-sensitive fiber-optic communication systems, such...
