Abstract:
An optical interconnect device on a silicon substrate is disclosed which includes a trench having two slanted side walls opposite to each other, a number of polymer waveguides formed in the trench, each including a straight portion and two end reflectors formed on the slanted side walls of the trench, a light source and an optical receiver disposed on an insulated layer on the silicon surface outside the trench. Conductive lines are patterned on the insulating layer and connects to the light source and the optical receiver. The light source and the optical receiver are aligned respectively to the two end reflectors of each polymer waveguide such that an optical path is formed from the light source device through the plurality of polymer waveguides to the optical receiver device, via reflection by the two end reflectors. A fabrication method to build the device is disclosed thereof.

Claim (Index 14):
A method of fabricating an optical interconnect apparatus, comprising:\n providing a silicon substrate having a top silicon surface; forming a trench on the top silicon surface; patterning a first and a second slanted side walls of the trench, wherein the first and second slanted sidewalls are opposite to each other; forming a plurality of polymer waveguides in the trench, comprising:\n depositing a first polymer cladding layer in the trench covering the first and second slanted side walls, followed by depositing a polymer core layer on the first polymer cladding layer; \n patterning the polymer core layer and covering the patterned polymer core layer with a second polymer cladding layer, wherein the plurality of polymer waveguides each has one straight portion and two slanted end reflectors; \n depositing an insulating layer on the silicon top surface outside the trench; patterning conductive lines in the insulating layer; growing solder bumps on conductive lines for flip chip mounting with bond pads; connecting a light source device with one of the conductive lines near the first slanted side wall of the trench and an optical receiver device with another one of the conductive lines near the second slanted side wall of the trench; and aligning the light source device and the optical receiver device with the slanted end reflectors of the plurality of polymer waveguides.
