Abstract
The linewidth enhancement factor α in an InGaAsP/InP multiple quantum well (MQW) laser has been determined from the spontaneous emission spectra below threshold. It is demonstrated that the measured value of α in the MQW laser is appreciably smaller than that in a conventional double heterostructure laser as expected from theoretical calculations.Keywords
