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 1):
An optical splitter module, comprising:\n a substrate having a silicon surface; a trench formed on the top silicon surface, wherein the trench comprises a first and a second slanted side walls opposite to each other, and an intrusion structure having a slanted front wall facing the first slanted side wall; a polymer waveguide formed in the trench, wherein the polymer waveguide comprises a first reflector formed on the first slanted side walls, a second reflector formed on the second slanted side wall, and a third reflector formed on the slanted front wall of the intrusion structure, wherein the third reflector blocks partially the polymer waveguide; an insulating layer deposed on the silicon surface outside the trench; a plurality of conductive lines patterned on the insulating layer; a light source device aligned to the first reflector and connected to a first of the plurality of conductive lines; a first optical receiver device aligned to the third reflector on the intrusion structure and connected to a third of the plurality of conductive lines; and a second optical receiver device aligned to the second reflector and connected to a second of the plurality of conductive lines; wherein an optical path comprises a first portion passing from the light source device through the polymer waveguide to the first optical receiver device, via reflection by the first and third reflectors, and a second portion passing from the light source device through the polymer waveguide to the second optical receiver device, via reflection by the first and the second reflectors.
