A new optical branching device for arrayed waveguides was proposed and experimentally demonstrated. This device consists of GaAlAs/GaAs waveguides. An input optical beam can be split into eleven waveguides. Moreover, it is shown that the phase relation between the lightwaves in branch waveguides is conserved.
