Abstract

A multimode interference coupler includes at least one supply waveguide and at least one output waveguide, wherein the coupler has along its longitudinal extent in the direction of the supply waveguide at least one longitudinal section in which the refractive index has a locally oscillating profile in a direction running substantially at right angles to the direction of the supply waveguide. A method for the structural configuration of such a multimode interference coupler.
