Non-transparent material is provided on the sidewalls of the transparent cover, which, in some implementations, can help reduce light leakage from the sides of the transparent cover or can help prevent stray light from entering the module. Fabrication techniques for making the modules also are described.

Abstract: Optoelectronic modules include an optoelectronic device and a transparent cover. A non-transparent material is provided on the sidewalls of the transparent cover, which can help reduce light leakage from the sides of the transparent cover or can help reduce stray light from entering the module. The modules can be fabricated, for example, in wafer-level processes. In some implementations, openings such as trenches are formed in a transparent wafer. The trenches then can be filled with a non-transparent material using, for example, a vacuum injection tool. When a wafer-stack including the trench-filled transparent wafer subsequently is separated into individual modules, the result is that each module can include a transparent cover having sidewalls that are covered by the non-transparent material.

Abstract: Optical stack assemblies and fabrication techniques thereof. The optical stack assembly includes first and second sub-assemblies, each of which include a substrate and a sub-structure fixed to the respective substrate. Each sub-structures includes a respective first edge feature and a respective second edge feature that project away from the substrate of that sub-structure, each second edge feature being disposed laterally closer to an outer periphery of the respective sub-structure than the first edge feature of the same sub-structure. The first edge feature of the first sub-structure is in direct contact with the first edge feature of the second sub¬structure, while the second edge feature of the first sub-structure and the second edge feature of the second sub-structure are attached to one another by adhesive. At least one of the first or second sub-structures includes an optical element on a same side of the sub-structure as the first and second edge features of that sub-structure. The optical element stack assembly further includes a spacer laterally surrounding, and moulded to, the first and second sub-assemblies.

Abstract: An optical module comprising: a plurality of active optoelectronic components each one mounted on a respective printed circuit board (PCB), wherein each active optoelectronic component is associated with a respective different optical channel; a plurality of optical assemblies, each one is substantially aligned over a different respective optical channel; and a spacer separating the active optoelectronic components and PCBs from the optical assemblies, wherein the optical assemblies are attached by adhesive directly to an optical assembly-side surface of the spacer. A first active optoelectronic component is separated, by the spacer, from a first optical assembly by a first distance and a second active optoelectronic component is separated, by the spacer, from a second optical assembly by a different second distance. Also contemplated is a method for fabricating an optical module that comprises: modifying a height of one or more extensions on a spacer to adjust for at least one of a focal length or tilt of at least one optical channel.

Abstract: The wafer-level manufacturing method makes possible to manufacture ultrathin optical devices such as opto-electronic modules. A clear encapsulation is applied to an initial wafer including active optical components and a wafer-size substrate. Thereon, a photostructurable spectral filter layer is produced which defines apertures. Then, trenches are produced which extend through the clear encapsulation and establish sidewalls of intermediate products. Then, an opaque encapsulation is applied to the intermediate products, thus filling the trenches and producing aperture stops. Cutting through the opaque encapsulation material present in the trenches, singulated optical modules are produced, wherein side walls of the intermediate products are covered by the opaque encapsulation material. The wafer-size substrate can be attached to a rigid carrier wafer during most process steps.
