Abstract
An optical coupler (1) for coupling light in/out of an optical receiving/emitting structure comprises an optical fiber (100), a supporting device (200) to support the optical fiber (100) comprising a supporting structure (210) in which the optical fiber is arranged, and a covering device (300) to cover the supporting structure. An end face (E100a) of the optical fiber (100) is configured to reflect the light to one of the supporting device (200) and the covering device (300) comprising a first area and a second area (210, 220, 310, 320) being provided with a respective different index of refraction or a change of the respective index of refraction so that the first area (310) is configured as one of an optical waveguide (311) and at least one optical lens (312) being embedded in the second area and forming an optical pathway in said one of the supporting device and the covering device.
