Abstract :
The frequency modulation characteristics of a two-electrode InGaAs/InP `as cleaved´ Fabry-Perot MQW laser reveal an FM enhancement of 1.7dB with an accompanying AM suppression of 2.3dB, relative to the uniformly pumped case, under small signal modulation at 900MHz. As a result the requirement for `vector modulation´ of multi-electrode FSK optical transmitters is relaxed
