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 18):
A method for modulating an optical signal comprising:\n propagating optical laser light down a semiconductor optical waveguide; and propagating RF signal along a pair of RF waveguides, wherein the semiconductor optical waveguide and the RF waveguide are configured in a traveling wave modulator structure to provide electro-optical coupling, wherein the traveling wave modulator structure comprise one or more compensation sections at which the relative phase of the propagating optical light and the propagating RF signal are corrected for a propagating speed differential and wherein the optical signal is modulated by a single RF signal.
