We report on linear and nonlinear optical properties of Disperse Red 1-doped solgel waveguides. The refractive-index and optical-propagation losses of the guiding layer were measured between 0.756 μm and 1.64 μm. The spectral broadening of the chromophore charge-transfer transition in the visible is modeled with a Voigt-profile function. In the telecommunications window the attenuation is dominated by the overtones of the O—H bonds vibration bands. The nonlinear optical coefficients were measured at different poling strengths with the Maker-fringe method. The nonlinear coefficient <i>d</i><sub>33</sub> was found to be 4.5 pm V<sup>−1</sup> at 1.58 μm for a poling field of 60 V μm<sup>−1</sup>.
