Abstract
A photoelectric coupling module includes a substrate, a photoelectric unit, and a lens module. The substrate carries at least two alignment marks for correct and absolute positioning of the lens module on the substrate. The photoelectric unit is positioned on the substrate. The lens module defines at least two through holes aligned with the alignment marks.
Claims8
A photoelectric coupling module, comprising:
- a substrate comprising a bearing surface, at least two alignment marks formed on the bearing surface;
- a photoelectric unit positioned on the bearing surface;
- and
- a lens module positioned on the substrate, and comprising a reflection surface, at least two first lenses, and at least two second lenses;
- optical axes of the first lenses crossing optical axes of the second lenses on the reflection surface;
- the lens module defining at least two through holes aligned with the alignment marks, the first lenses aligned with the photoelectric unit.
The photoelectric coupling module of claim 6, wherein the number of the through holes is two, the two through holes are positioned at two ends of the first recess, the two through holes are lineally arrayed along a direction parallel with an extending direction of the first recess.
