Abstract. We consider graviton-induced bremsstrahlung at future e + e - colliders in both the ADD and RS models, with emphasis on the photon perpendicular momentum and angular distribution. The photon spectrum is shown to be harder than in the standard model, and there is an enhancement for photons making large angles with respect to the beam. In the ADD scenario, the excess at large photon perpendicular momenta should be measurable for values of the cut-off up to about twice times the CM energy. In the RS scenario, radiative return to graviton resonances below the CM energy can lead to large enhancements of the cross section.
