Abstract
To open up a 1-microm waveband for photonic transport systems, we developed a hybrid and harmonically mode-locked semiconductor laser (MLL) that can transmit return-to-zero (RZ) optical signals at data rates on the order of gigabits per second. A single-mode hole-assisted fiber (HAF) was also developed for use as a 1-microm waveband signal transmission line. A stable optical pulse train with a repetition rate of 9.953 GHz, pulse width of 22 ps, and low timing jitter of 120 fs was obtained from a 1035-nm harmonically MLL. With these devices, we successfully demonstrated 1-microm waveband error-free transmission of a high-speed 10-Gbps RZ signal over a long distance of 7 km.
