Abstract:
The application discloses a polymer-based optical splitter on a silicon surface. A trench is formed on the silicon surface and a polymer waveguide having three 45 degree reflectors is patterned in the trench. The trench has two slanted side walls opposite to each other. Two reflectors of the polymer waveguide are arranged on the two slanted side walls. An intrusion structure with a slanted front wall is located in the middle of the waveguide and the third reflector is formed on the slanted front wall. The first reflector receives an optical input source, the second reflector is aligned to return light to the end optical receiver. The third reflector functions as a light splitter and is aligned to an intermediate optical receiver. Light splitting ratio is determined by the third reflector size relative to the waveguide cross section near the third reflector. A fabrication method is disclosed thereof.

Claim (Index 4):
The optical splitter module of  claim 1 , wherein the first slanted side wall of the trench has a slanted angle approximately set at 45 degrees to align optically to the light source device, wherein the second slanted side wall of the trench has a slanted angle approximately set at 45 degrees to align optically to the second optical receiver device, and wherein the slanted front wall of the intrusion structure has a slanted angle approximately set at 45 degrees to align optically to the first optical receiver device.
