ABSTRACT:
Integrated optical branching arrangement has a monomode waveguide 1 and a Y-branch waveguide 2. The waveguides conjointly define an abutting junction having a lateral offset (d). This is particularly advantageous when curved monomode waveguides are used. The offset is suitable for setting the power distribution ratio. The integrated optical branching arrangement can be applied to ion-exchanged devices in glass and to wavelength multiplexers.
