Abstract
A polarisation control device having a polarisation converter (22) in a first section (B)of an optical waveguide (15) with a gradually varying asymmetrical cross - sectional (transverse) profile and an active phase shifter (38) in a second section (C) of the optical waveguide whose birefringence is adjustable by a relative phase controller. The polarisation converter (22) converts an orthogonal fundamental mode (TE or TM) into a hybridised signal present in the active phase shifter (38). The first and second sections (B, C) of waveguide are joined to one another to form a single continuous waveguide (15), which can significantly reduce interfacial reflections.
