Abstract
''Excess'' polarization of the spontaneous emission (EPSE) of diode la sers at low injection levels, being more pronounced in degraded specim ens, has been observed. A model of EPSE is proposed, involving tunnel radiative recombination of electrons and light holes at inhomogeneitie s of the p-n junction. Separating EPSE from the polarization effect ca used by elastic deformation enables the strain in the active region of laser heterostructures to be determined. Copyright (C) 1996 Elsevier Science Ltd
