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 19):
The method of  claim 18  wherein the one or more compensation sections are three or more compensation sections and wherein each compensation section independently has altered doping of the semiconductor waveguide interfacing with the RF waveguide, an extended portion of optical waveguide not interfacing with the RF waveguide, or an extended portion of RF waveguide not interfacing with the semiconductor optical waveguide.
