摘要：

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.
