Abstract
The invention provides an optical waveguide and a method of making an optical waveguide. The waveguide has a curved section having an asymmetric refractive index profile, in which the refractive index varies asymmetrically across the waveguide cross-section in dependence on the radius of the curved section of the waveguide.

An optical waveguide having a curved section in which, in the curved section, the waveguide has an asymmetric refractive index profile, in which the refractive index varies asymmetrically across the cross-section of the waveguide in dependence on the radius of the curved section of the waveguide.
A method of making an optical waveguide comprising forming a waveguide on a substrate, the waveguide including at least one curved section and varying the refractive index profile of the waveguide across its width in dependence on the radius of the curve.
