Abstract
The disclosure relates to an optical splitter including two waveguides on either side of an axis. Each waveguide includes a first segment and a second segment that are closer to the axis than the rest of the waveguide. The first segments are optically coupled and the second segments are optically coupled. Each guide includes between the first and second segment, starting from the first segment, a first curved section including in succession a curvature the concavity of which is turned the side opposite the axis then a curvature the concavity of which is turned towards the axis, and starting from the second segment a second curved section including in succession a curvature the concavity of which is turned the side opposite the axis then a curvature the concavity of which is turned towards the axis. The first curved sections of the two waveguides are curved differently.
