Optical-electric converting element and optical-electric converting module

摘要

An optical-electric converting element includes a lower surface and a side surface. The lower surface defines a cavity. A bottom portion of the cavity forms at least one first light-gathering coupling lens and at least one first light-emitting coupling lens. A diameter of the at least one first light-receiving coupling lens is equal to d1, and a diameter of the at least one first light-emitting coupling lenses is equal to d2. The side surface perpendicularly connects to the lower surface. The side surface forms at least one second light-receiving coupling lens and at least one second light-emitting coupling lens. A diameter of the at least one second light-emitting coupling lens is equal to d3, a diameter of the at least one second light-receiving coupling lens is equal to d4; wherein d1>d3 and d4>d2.
