Abstract
Using optical gain measurements and calculated optical gain spectra we anal yse the various contributions to the threshold current observed for laser d iodes. Our model is based on band-to-band transitions and includes internal polarization fields as well as multiple quantum wells. Besides good agreem ent between experiment and theory, our model explains the characteristic de pendence of the threshold current on emission wavelength and well number.
