1.3microns Semiconductor Laser Power Amplifier.
01 January 1989
The feasibility of a semiconductor laser power amplifier is demonstrated. In a 3.4 GBit/s system, the -14.5 dBm input from a directly modulated DFB laser is boosted to +10.3 dBm of which +4.8 dBm is coupled into the transmission fiber. The penalty, caused by amplifier noise and pattern effects due to gain saturation, is less than 0.5 dB.
