SOI-based vertically-splitting optical waveguides for optical interconnects

A SOI-based three-dimensional vertically-splitting optical waveguides for optical interconnects is experimentally demonstrated first time. The optical insertion loss of -3.46 dB is experimentally obtained for the proposed splitter with tuneable splitting ratio from 4.9:1 to 1.2:1. Compared with the straight waveguide, the proposed waveguide have excess loss of 0.51 dB.
