Abstract
Two-tone testing was performed on a laboratory fiber optic link with L iNbO3 traveling wave linearized directional coupler modulators. The th ird-order distortion was measured at 500 MHz and 1000 MHz and the spur -free dynamic range was determined. Two modulator configurations, with either one or two passive bias sections, were tested and the results were compared with measurements of simple directional coupler modulato rs. A 9.5-11 dB improvement in the dynamic range was found in the link s employing the linearized modulators.
