Abstract:
1. An optical-electric converting element, comprising: a lower surface defining a first cavity, the first cavity comprising a bottom portion, the bottom portion forming at least one first light-receiving coupling lens and at least one first light-emitting coupling lens, a diameter of the at least one first light-receiving coupling lens being equal to d1, and a diameter of the at least one first light-emitting coupling lenses being equal to d2; and a side surface perpendicularly connecting to the lower surface, the side surface forming 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 being equal to d3, a diameter of the at least one second light-receiving coupling lens being equal to d4; wherein d1>d3 and d4>d2.
