Abstract

An optical input section for a coherent optical receiver based on polarisation diversity include means for a different order mode conversion (25.2 in 41) followed means for different order mode splitting (25.3 in 41) before or after means for mixing (42, 43) of optical signals. Since devices for different order mode splitting and for mixing have simple integrable realizations without metallized elements, t.w. (a)symmetric Y-junctions and 3dB-power couplers, respectively, the optical input section is realizable without such metallized elements. <IMAGE>
