Abstract
Abstract A method for manufacturing a molded waveguide (50) is provided. A first cladding layer (20) is provided. Channels (21) are formed in the first cladding layer (20). A second cladding layer (40) is subsequently provided. The channels (21) in the first cladding layer (20) are then filled with an optically transparent polymer. The second cladding layer (40) is subsequently affixed over the channels (21) of the first cladding layer (20), thereby enclosing the channels (21).

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
160 words
A method for fabricating an optical electronic module comprising: providing an interconnect board having standard electronic components, output leads, and at least one interface pad, the at least one interface pad connects the standard electronic components and the output leads interactively; attaching a molded split waveguide to the interconnect board, the molded split waveguide comprising a channel that splits into at least two channels, an alignment guide, and a optical component having an active area and an output pad, the channel and the at least two channels and the alignment guide are molded therein and the optical component is mounted onto the molded split waveguide aligning the active area of the optical component to the channel; thereby enabling the optical component to respond to an optical signal traveling through the molded split waveguide; and connecting the interface pad of the interconnect board with the output pad of the split waveguide, thereby interconnecting the standard electronic components to the optical component.
Claim 2
Independent Claim
160 words
A method for fabricating an optical electronic module comprising: providing an interconnect board having standard electronic components, output leads, and at least one interface pad, the at least one interface pad connects the standard electronic components and the output leads interactively; attaching a molded split waveguide to the interconnect board, the molded split waveguide comprising a channel that splits into at least two channels, an alignment guide, and a optical component having an active area and an output pad, the channel and the at least two channels and the alignment guide are molded therein and the optical component is mounted onto the molded split waveguide aligning the active area of the optical component to the channel; thereby enabling the optical component to respond to an optical signal traveling through the molded split waveguide; and connecting the interface pad of the interconnect board with the output pad of the split waveguide, thereby interconnecting the standard electronic components to the optical component.
