Abstract
An improved experimental method for measuring gain and refractive inde x in semiconductor lasers from below-threshold amplified spontaneous e mission spectra is presented. Broad-area, as opposed to narrow-stripe width, diode lasers and a far-field spatial filtering technique are em ployed to eliminate uncertainties associated with lateral waveguiding and carrier confinement.
