%X By means of two dimension beam propagation method(2D-BPM) with high order Pade approximation,behaviors of SOI waveguide based bend intersections with variant bending radius are simulated and analized.The result shows that crosstalk of intersections decreases with the increase of bending radius and intersecting angle.Furthermore,loss and crosstalk characteristics of bend intersections formed by sine bend,cosine bend and arc bend are compared.Sine bend based structures are proved that it can present lowest loss and smallest crosstalk properties among the three and may find their wide application in the design of bend intersections and other more complicated photonic devices and circuits.
