OPTICAL MODULATION METHOD USING PARALLEL TOPOLOGY OF OPTICAL MODULATORS AND PARALLEL MATCHING

摘要

PURPOSE: An optical modulation method using parallel topology of optical modulators and parallel matching is provided to improve the linearity of the optical modulation. CONSTITUTION: An optical modulation method using parallel topology of optical modulators and parallel matching according to the present invention includes a first optical modulator(301) and at least one second optical modulators(302). The first optical modulator(301) optically modulates an electrical signal. The plurality of second optical modulators(302) are coupled to the first optical modulator in parallel topology and optically modulate the electrical signal so as to perform compensation for the non-linearity of the first optical modulator.
