Abstract: A polarisation converter for a photonic integrated circuit. The polarisation converter comprises a first semiconductor layer, a second semiconductor layer and a third semiconductor layer. The second semiconductor layer comprises, when viewed in a cross-sectional plane perpendicular a light propagation axis, a first portion thicker than a second portion. The second semiconductor layer is between, and in contact with, the first semiconductor layer and the third semiconductor layer.

Abstract: A light polarisation converter for a photonic integrated circuit, comprising a first layer. The first layer comprises a first surface and a second surface. The second surface is offset from the first surface along a first axis and a second axis. The first axis is perpendicular to the first surface. The second axis is parallel to the first surface. The light polarisation converter comprises a second layer and a waveguide. The waveguide is between, and in contact with, the first layer and the second layer. The waveguide comprises a first waveguide portion in contact with the first surface, and a second waveguide portion in contact with the second surface. The second waveguide portion is offset from the first waveguide portion. The first waveguide portion has a first thickness different to a second thickness of the first waveguide portion. The first thickness and the second thickness are perpendicular the first surface.
