A 1×8 power splitter made of UV curable optical epoxy was proposed and fabricated. A novel asymmetrical structure was utilized in power splitting scheme to enable a uniform distribution of energy among all branches. By the use of laser direct writing process and high precision translation stages, the prototyping process was completed within a short fabrication phase of 5 min. Power splitting test was made and power from output ports were analyzed. The splitter has a nearly-equal output for all channels except for one with a 4% fluctuation. The asymmetric design and mask-less fabrication make it possible to realize an effective and high-yield production of this device.
