Abstract:
Optical modulators with semiconductor based optical waveguides interacting with an RF waveguide in a traveling wave structure. The semiconductor optical waveguide generally comprise a p-n junction along the waveguide. To reduce the phase walk-off between the optical signal and the RF signal, the traveling wave structure can comprise one or more compensation sections where the phase walk-off is reversed. The compensation sections can comprise a change in dopant concentrations, extra length for the optical waveguide and/or extra length for the RF waveguide. Corresponding methods are described.

Claim (Index 1):
An optical modulator comprising a semiconductor-based optical waveguide and a pair of RF waveguides, wherein the optical waveguide and the RF waveguide are configured with coupling regions to provide an RF electromagnetic field within the optical waveguide and with one or more compensation sections with lengths of either optical waveguide or RF waveguide that have substantially reduced or eliminated electro-optical coupling, wherein the RF waveguides form a continuous waveguide structure through the one or more compensation sections.
