## Abstract A novel threeβbranch optical power divider with a diamondlike microprism of low index is proposed. The input power can be equally distributed to three output waveguides at large branching angles. The total transmitted power is as high as 97.7% at ΞΈ = 3Β°, which is higher than that report
when the coupler returned to 20ΠC, showing that the effect is reversible with temperature. In summary, the proposed process permits the fabrication of couplers with polarization extinction similar to the fiber's. Moreover, this kind of device presents very low loss, and exhibits good mechanical and
