| 摘要 |
An optical waveguide structure is provided wherein a controller is configured to provide a TE control voltage to a first set of control electrodes in a first electrooptic functional region and a TM control voltage to a second set of control electrodes in a second electrooptic functional region. The TE control voltage and the first electrooptic functional region are configured to alter the TE polarization mode of an optical signal propagating along the waveguide core through the first electrooptic functional region to a substantially greater extent than the TM polarization mode of the optical signal. Further, the TM control voltage and the second electrooptic functional region are configured to alter the TM polarization mode of an optical signal propagating along the waveguide core through the second electrooptic functional region to a substantially greater extent than the TE polarization mode of the optical signal. Additional embodiments and features are disclosed and claimed.
