Abstract

A model for the determination of the threshold current of quantum well laser is presented, using a no-k-selection rule for the gain calculation and taking into consideration propaga-tion and confinement properties of the waveguide. A graded refractive index separate confinement heterostructure (GRIN-SCH) was fabricated by molecular beam epitaxy. Threshold currents of 11 mA are obtained on ridg (3 x 200 4m) devices from a wafer for which the broad area threshold density is 380 A/cm². Gain measurements performed on these lasers show the good fit between experimental spectra and theoretical spectra obtained with the model.
