We report on measurements of the spontaneous emission factor for oxide-confined InGaAs vertical cavity surface emitting lasers. The spontaneous emission factor is determined as a function of the active layer volume from the measurement of small-signal harmonic distortion at threshold. For a 333 mm oxide aperture device we obtain spontaneous emission factor of 4.2 •10 at room temperature. ©1997 American Institute of Physics. @S0003-6951 ~97!03501-8#
