Abstract We propose to measure the contrast of Fabry-Perot resonances in low-finesse (end face polished) integrated optical resonators to determine an upper limit of the waveguide attenuation coefficient. The method is discussed; its absolute accuracy increases with decreasing loss. As example, experimental results are presented for 3 and 10 μm wide Ti: LiNbO3 strip guides; the attenuation coefficients are 0.46 dB/cm (EH11) in the narrower guide at λ=0.63 μm, respectively 0.19 dB/cm (EH11) and 0.09 dB/cm (HE11) in the 10 μm wide guide at λ=1.15 μm.
