Abstract

A polarisation control device having a polarisation converter in a first section of optical waveguide with a gradually varying asymmetrical cross-sectional (transverse) profile and an active phase shifter in a second section of optical waveguide whose birefringence is adjustable by a relative phase controller. The polarisation converter converts an orthogonal fundamental mode (TE or TM) into a hybridised signal present in the active phase shifter. The first and second sections of waveguide are joined to one another to form a single continuous waveguide, which can significantly reduce interfacial reflections. The invention teaches the introduction of a selectable degree of asymmetry to a section of planar optical waveguide after growth of that waveguide to form the polarisation converter. This feature enables the use of lower efficiency mode convertors to give far greater control over fabrication tolerances, leading to increased yield.
