Abstract
An optical modulator for fiberoptic telecommunications is disclosed in which the optical signal velocity in the modulator waveguide and the electrical signal velocity in the traveling wave signal electrode are purposely mismatched by a factor of up to about 4. On-chip integrated inductors and capacitors are implemented to achieve the velocity mismatch. Improved electro-optic characteristics, such as return loss and sharper cut-off bandwidth are obtained.
