Negative chirp modulation of optical transmitters is needed for the optimal performance of high bit-rate transmission in optical fiber systems operating at nonzero dispersion window at 1.5 μm. In this paper several approaches to achieving any fixed chirp value for LiNbO3modulators are proposed, Experimental results of impedance matched devices on x-cut lithium niobate with chirp values of /spl plusmn/0.7 and /spl plusmn/1.0 are presented. By tuning the modulators bias point, the chirp value can be adjusted linearly around the designed value without degrading other performances.
