Abstract:
FPC-based optical interconnect modules with glass interposer connecting a VCSEL laser to a fiber ribbon cable is described. Improved optical coupling between VCSEL/PD and polymer waveguides are achieved by monolithically integrating micro-lenses and waveguides on the rear side of glass interposer and active devices on the front side. The waveguide has a vertical portion at one end of a horizontal trench portion joined by a 45 degree sidewall. A method of fabrication includes: providing a glass interposer, an array of micro lenses and an array of polymer waveguides having 45 degree tapered ends as reflectors on one surface, and depositing a metal layer and patterning the metal layer into transmission lines on the second surface of the glass substrate, growing bonding pillars for flip chip mounting and assembling active optical devices on the second surface of the glass to connect with the transmission lines.

Claim (Index 18):
A method of fabricating an optical interconnect apparatus in  claim 17 , wherein preparing an array of polymer waveguides comprises:\n providing a temporary substrate as a support; depositing a first polymer cladding layer on the temporary substrate; patterning the first polymer cladding layer into a trench on the temporary substrate and a tapered side wall by applying multiple exposure patterning techniques, wherein patterning the tapered side wall by applying the multiple exposure patterning techniques include exposing different locations of the tapered side wall with a plurality of exposure energy levels, wherein the plurality of exposure energy levels includes keeping light source exposure energy output constant and varying exposure time on the tapered sidewall, or keeping light source exposure energy output constant and varying exposure aperture size; depositing a first core layer on the top cladding layer and filling into the trench and also on top of the tapered side wall; planarizing the first core layer to remove excess first core layer from the top surface of the first polymer cladding layer; depositing a second cladding layer; patterning the second cladding layer to form a vertical cavity aligned with the tapered side wall; depositing a second core layer and filling the vertical cavity; planarizing the second core layer to remove excess of the second core layer from the second cladding layer; and removing the temporary substrate.
