    Abstract: 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.

    Abstract: The invention relates to a polarisation transformer/PMD compensator chip that is located in a substrate (SUB) in a weak or non-double refractive crystal section with a mode transformation between circular polarisations. The polarisation transformer/PMD compensator chip contains other polarisation actuators in the form of quarter wave plates, which enable the transformation of the polarisation-receiving optical waveguides (PMFA, PMFB) situated upstream or downstream from circular polarisation to a main polarisation. Modules of this type can be cascaded to produce a simple polarisation mode dispersion compensator.

    Abstract: An opto-electronic device (1) comprising a directional coupler (11) provided with a first waveguide (1) to receive incoming electromagnetic radiation, said first guide comprising a guiding region (3) of electro-optic material. Moreover, the directional coupler comprises a second waveguide (2) into which can be coupled at least a first portion of said incoming radiation and provided with a port for radiation being output. The opto-electronic device is equipped with a structure for generating (12, 13) a controlling electric field (E RF ) at least inside said first guide (1) of the directional coupler and such as to cause in said electro-optic material polarization conversion of at least part of said incoming radiation. By means of this polarization conversion it is possible to control the power of the radiation being output from the second waveguide, producing a modulator, a changeover switch, an attenuator or an open-or-closed switch.

    Abstract: An optical signal may be received into orthogonal linearly polarized modes of a transmission optical waveguide, the transmission waveguide including first and second transverse-coupling segments thereof. Optical signal polarized along one polarization direction may be substantially completely transferred from the transmission waveguide into a first transverse-coupled waveguide, the first transverse-coupled waveguide being optically transverse-coupled to the first transverse-coupling segment of the transmission waveguide. Optical signalpolarized along the other polarization direction may be substantially completely transferred from the transmission waveguide into a second transverse-coupled waveguide, the second transverse-coupled waveguide being optically transverse-coupled to the second transverse-coupling segment of the transmission waveguide. The optical signals carried by the first and second transverse-coupled waveguides may be combined into a single waveguide. The polarization directions of the transmission waveguide may be rotated about 90° between the first and second transverse-coupling segments
