| Abstract: | In the previous approach,the 2-D or 3-D optical waveguides on the substrate region are often calculated with beam propagation method(BPM).A new method is presented based on the finite element and beam propagation method.For simplicity,the 2-D optical waveguide is only designed and calculated on the substrate region,and the power transmittance of the Y-branch waveguide is also got,which is approximate 52.8%.The result is in good agreement with the others. |
