摘要:

The linewidth enhancement factor &agr; 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 &agr; in the MQW laser is appreciably smaller than that in a conventional double heterostructure laser as expected from theoretical calculations.
