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 a-value for the strained lasers measured under dynamic conditions is 2.4±0.6
