Abstract
An optical coupling element includes a lower surface, an upper surface, and a side surface. The lower surface defines a first cavity. The first cavity includes a bottom portion. The bottom portion forms at least two first light coupling lenses. A diameter of each first light coupling lens is equal to d1. The upper surface faces away from the lower surface, and defines a second cavity. The second cavity includes a reflecting surface. The side surface perpendicularly connects to the lower surface. The side surface forms at least two second light coupling lenses. A diameter of each second light coupling lens is equal to d2, and d1>d2.
