Abstract
Optical waveguiding part (), which waveguiding part is arranged to convey light through an output facet () of the waveguiding part, which waveguiding part comprises a ridge waveguide comprising a semiconductor substrate () and a semiconductor light-conveying ridge, wherein the output facet is set at an angle (α) in relation to a main direction (z) of light along the said waveguide, so that light travelling in the waveguide along said main direction has an angle of incidence towards the facet of between 2° and 14° and is reflected towards a first side () of the said ridge, wherein the waveguide comprises an MMI (Multi Mode Interferometer) (), arranged to create an output image substantially at the output facet.
