ABSTRACT:
A Mach-Zehnder interferometer type modulator, constructed of first and second optical waveguides, first and second electrodes cooperating with the same, and a driving voltage source, wherein a driving voltage source is constructed of first and second driving units which drive independently the first and second electrodes in accordance with a data input and wherein the first and second driving units apply first and second driving voltages, individually determined, to the first and second electrodes.
