Abstract

An optical device includes at least one multi mode interference (MMI) waveguide and at least one Bragg-grating structure [50]. At least one access waveguide [1,2] is arranged on a first side of the MMI-waveguide and at least one access waveguide is arranged on a second side of the MMI waveguide, the first and second sides being the short sides of the MMI-waveguide. The access waveguides are arranged with a so-called taper structure, and the Bragg-grating structure is arranged in the MMI-waveguide. The Bragg-grating may be arranged in the centre of the MMI-waveguide or in an offset relation to the centre of the MMI-waveguide.
