Abstract :
Design of low-loss power divider with a trapezoidal microprism of low-index is proposed. The input power can be divided into three equal ones at output waveguides for large branching angles. The total transmitted power is as high as 97.7% for a branching angle of 4 °. which is greater than that reported (88%). Moreover, by only varying the refractive index of the microprism, the powers entering the central and the side branches can be adjusted to a desired ratio.
