Abstract
A variable chirp electro-optic modulator is provided that uses a single modulation signal. The modulator has several optical paths in the proximity of one or more modulation electrodes which are driven equally by a single modulation source. The amount of chirp desired of the modulator is controlled by varying the optical amplitude or phase of the light in the different paths.
