Crosstalk reduction using tapered intersecting waveguides has been proposed and demonstrated experimentally. The crosstalk with a small intersection angle of up to 20° was theoretically investigated, by applying coupled mode theory. Experimental results show that the crosstalks between wide taper intersecting waveguides with the angles of 13 to 20° are decreased with respect to the crosstalk of the intersecting linear waveguide.
