4 Gbit/s direct modulation of 1.3 m InGaAsp/Inp semiconductor lasers /
It is confirmed that the multiplexer and the semiconductor laser can be operated up to 4 Gbit/s with pseudorandom pulse pattern. The relaxation oscillation, pattern effect and tailing effect of the semiconductor laser are alsostudied. It is confirmed that eye degradation is predominantly due to fluc...
