Abstract	We present the measurements and the analysis of nonlinearity of Ge- and InGaAs-photodiodes responsivity measured at high irradiance levels (up to ∼ 90 mW / mm$^{2}$) in the near infrared. The nonlinearity was measured using a fiber-optics-based setup which employs the Differential Spectral Responsivity (DSR) technique. The measurements of the nonlinearity were carried out at different laser beam diameters with fiber optic attachment as well as open-beam. All photodiodes investigated present a nonlinarity of the saturation type, which depends on the beam diameter of the radiation source.
