英文摘要	A device for optically coupling a light emitting diode and a radiation pickup such as an optical fiber. The light emitting diode element includes at least one emissive section within an active layer where a part of the light irradiation does not emerge from the diode element if it is emitted at an excessive angle of incidence. A lenticular element in the form of either a semi-cylindrical lens or a semi-toroidal lens is associated with the emissive section. In one form, the device includes a circular central lens and a plurality of semi-toroidal lens concentric with respect to the central lens and associated with annular emissive sections.
