Scheme for controlling polarization in waveguides |
摘要 |
The present invention present a means for addressing PDL, PMD, and other polarization-related performance issues in optical components and systems. In accordance with one embodiment of the present invention, an integrated optical device is provided. The device comprises: (i) first and second optical waveguide arms arranged to define an optical signal splitting region near an input side of the integrated optical device and an optical signal combining region near an output side of the integrated optical device and (ii) a functional region between the optical signal splitting and combining regions. The first and second optical waveguide arms comprise first and second waveguide cores passing through a first electrooptic portion of the functional region. First and second sets of control electrodes are positioned to generate electric fields in the first and second portions of the functional region. The first set of control electrodes and the first waveguide core are positioned to be TE mode predominant and the second set of control electrodes and the second waveguide core are positioned to be TM mode predominant.
