Research output: Contribution to journalArticle


The linewidth enhancement factor, α, has been measured in unstrained and 1% compressively strained InGaAsP lasers operating under both static and dynamic conditions. Values of 4 ± 0.5 for the unstrained lasers and 2.1 ± 0.5 for the strained devices are found under DC conditions. The α-value for the strained lasers measured under dynamic conditions is 2.4 ± 0.6.
