Abstract
Three techniques for the measurement of propagation losses of single mode integrated optical waveguides are compared. The insertion loss measurement technique and the backcoupling method are suitable for the measurement of attenuation values alpha L>or=1. The resonator techniques give small relative mean errors of the attenuation only for high finesse resonators, which can, in principle, be realized by a waveguide Fabry-Perot resonator with high reflecting endfaces. A more convenient solution, however, is an additional ring resonator on the integrated optical chip.
