Abstract
A variable chirp optical modulator is provided in which an optical waveguide is split for part of its length into first and second waveguide arms. Electrode pairs are utilized to provide modulating electric fields in a portion of the first and second waveguide arms. The optical lengths of the portions of the first and second waveguide arms that are subject to the modulating electric fields are different and are selected to provide a predetermined level of chirp. By controlling the optical power split from the optical waveguide to the first and second arms, the chirp is varied from the predetermined level.
