ABSTRACT:
An integrated optical circuit comprises a first device and a second device, which devices are connected by a polarization convertor. The polarization convertor has one or more curved sections of a waveguide, integrated in the optical circuit. The conversion ratio is determined in part by the radius of curvature of the curved sections.
