PHOTOELECTRIC COUPLING MODULE

摘要

A photoelectric coupling module includes a substrate, a photoelectric unit, and a lens module. The photoelectric unit is positioned on the substrate, and includes at least one light emitter and at least one light receiver. The lens module is positioned on the substrate, and includes a reflection surface, at least two first lenses, and at least two coupling portions. Each coupling portion includes a receiving part and a second lens received in the receiving part. Optical axes of the first lenses cross optical axes of the second lenses of the at least two coupling portions on the reflection surface. The first lenses are aligned with the at least one light emitter and the at least one light receiver.

1. A photoelectric coupling module, comprising:
a substrate comprising a bearing surface; a photoelectric unit positioned on the bearing surface, and comprising at least one light emitter and at least one light receiver; a lens module positioned on the bearing surface, and comprising a top surface, a bottom surface opposite to the top surface, and a side surface connected between the top surface and the bottom surface; the lens module defining a first recess in the top surface, a second recess on the bottom surface, and a third recess on the side surface; the first recess comprising a reflection surface tilting about 45 degrees relative to the bearing surface; the second recess comprising a lower surface parallel to the bearing surface; the third recess comprising a connecting surface perpendicular to the bearing surface; the reflection surface facing the connecting surface and the lower surface; at least two first lenses formed on the bottom surface; and at least two coupling portions extending outward from the connecting surface; each coupling portion comprising a receiving part and a second lens received in the receiving part; optical axes of the first lenses crossing optical axes of the second lenses of the at least two coupling portions on the reflection surface; the first lenses aligned with the at least one light emitter and the at least one light receiver.
