Abstract
Integrated optic Y-branching waveguides with an asymmetric branching ratio are proposed by using a novel and simple waveguide configuration. Realisation of a controllable wide branching ratio, simply by shifting the centre axes of the input taper waveguide and the branching waveguide group is clarified both theoretically and experimentally. 1 × 2 Y-branch splitters with an asymmetric branching ratio of 50.0 ~ 75.6%, a low excess loss of <0.2 dB and based on planar lightwave circuits are demonstrated.Keywords
