Analysis of waveguide-splitter-junction in high-index Silicon-On-Insulator waveguides.
We propose and analyze a new type of four ports structure for ultra-compact waveguide splitting. This structure differs from most existing ultra-compact waveguide splitters by introducing complete symmetry between the input and output ports. Maximum overall throughput predicted is ~81% where reflection and crosstalk are <1%. A 2D photonic-crystal implementation concept. Is presented as well. Concept of operation and simulation results are provided. The trade-off between performances and functionality is discussed.
