Abstract:
A glass substrate as a platform for a high speed optical interconnect is disclosed. An optical engine is mounted on the top surface and a polymer waveguide on the bottom surface of the glass substrate. A metal plate can be included for mechanical support. The optical engine includes conductive lines patterned into the glass and active optical devices bonded with the conductive lines. An anisotropic conductive film (ACF) connects the optical engine with a printed circuit board. The waveguide, attached parallel to the bottom surface of the glass substrate, includes a core structure, a 45 degree tapered portion at one end of the core structure, used as a light reflector. An optical fiber connector is attached to the far end of the polymer waveguide. The optical path is formed from the active optical device on the top surface, through the glass substrate and the polymer waveguide, to the optical fiber connector on the bottom surface of the glass substrate.

Claim (Index 18):
A method of fabricating an optical interconnect apparatus in  claim 17 , wherein preparing a polymer waveguide having a 45 degree reflector portion at a first end 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 and a 45 degree side wall into a trench on the temporary substrate by applying multiple exposure lithography patterning techniques, wherein patterning the 45 degree side wall by applying the multiple exposure lithography patterning techniques includes 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 45 degree 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.
