Abstract

A novel design of multimode light power splitter is proposed and fabricated by using secondary asymmetric Y branches. An almost equally divided output among output terminals is obtained experimentally. Maskless laser direct writing technique is applied in the fabrication process to facilitate the formation of power splitters by ultraviolet curable polymer. The analysis of the performances of both four-port and eight-port devices shows that these two dividers obtain a power splitting uniformity of more than 95%.
