Abstract (en)
[origin: WO2008092825A1] An optical branching element (100) has an optical conductor track arrangement (LB) which extends from a first side (S1) to a second side (S1) of an optical chip of the optical branching element. The conductor track arrangement (LB) has a plurality of branching nodes (K1) where in each case one conductor track section (LB1) branches to form a plurality of conductor track sections (LB2, LB3). At a branching node (K1), the light output injected by way of a first conductor track section (LB1) is distributed to the conductor track sections (LB2, LB3), which are connected downstream and branch off from the branching node (K1), in a non-uniform manner. Receiving units (R1) which exhibit a larger distance from a transmission unit (T) than other receiving units (R2) are connected to those conductor track sections (LB2) of the optical branching element which have a lower insertion loss due to the non-uniform ratio of the distribution of the light output.
