    Abstract: A device for polarisation-independent transmission of light between two waveguide arrays (501, 511), including an imaging means (506), which is disposed between at least two means (502, 505, 507, 509) for polarisation-dependent displacement of converging and diverging beams proceeding to and from the waveguides (501, 511); and a plurality of polarisation rotation means. The displacement means (502, 505, 507, 509) may be birefringent crystals of thickness less than is required for collimated beams. The rotation means can include suitably disposed half-wave plates (503, 509) for polarisation equalisation, and Faraday rotators (504, 508).

    Abstract: An optical filter, comprising a first optical waveguide (3), a second optical waveguide (6) and means for expanding light from first optical waveguide into a beam (4), and at least one optical flat (1) inserted partially into the beam so that a fraction of the light passes through each optical flat (1) and a means for focussing the light into the second optical waveguide (7). In its simplest form the device has a Mach-Zehnder (sinusoidal) transmission characteristic. The filter can be tuned both in wavelength and extinction either mechanically or electrically. More complex (non-sinusoidal) characteristics can also be obtained. A number of implementations are disclosed.
