Abstract :
CW and high-speed (100 ps pulse) single-longitudinal-mode operation has been achieved with a short-coupled-cavity (SCC) InGaAsP injection laser (in the 1.3 ¿m to 1.55 ¿m spectral range) consisting of a short (50¿80 ¿m) cleaved laser and a short (30¿80 ¿m) external air resonator with a high-reflectivity mirror. The SCC laser resonator combines the advantages of both a short-cavity laser and a coupled-cavity laser for effective mode selection. Single-mode operation has been maintained at modulation rates of 2 Gbit/s.
