Abstract
A tuneable electro-optic modulator (1) comprising first and second spaced apart output optical waveguides (2, 3), each output optical waveguide comprising a coupled portion (12) optically coupled to a corresponding coupled portion (13) of the other output optical waveguide, the coupled portions defining a coupling region (14) therebetween; an optical source adapted to symmetrically provide an optical signal to the first and second output optical waveguides; a portion of each of the output optical waveguides having a signal electrode (6, 7) thereon; the modulator further comprising a central optical waveguide (15), at least a portion of which is arranged in the coupling region, the central optical waveguide having a tuning electrode (16) thereon.
