Abstract
The inventive optical component assembly advantageously enables a multi-waveguide optical component (such as the inventive optical fiber coupler array, a multi-core optical fiber, etc.), to be coupled to at least one waveguide of an optical device at a predefined coupling angle. The optical component assembly of the present invention comprises a multi-waveguide optical component with an output end, a prism having an input surface, an output surface, and an internal reflective surface with a predefined reflection angle, and a GRIN lens, positioned between the component output end and the prism input surface, along a longitudinal axis of the multi-waveguide optical component. In accordance with the present invention, the length of the GRIN lens, and its refractive index gradient profile are optimized to form an optical image of the output end of the multi-waveguide optical component, at the output surface of the prism, thus enabling the output surface of the prism to be coupled to at least one waveguide of an optical device, with the predefined reflection angle corresponding to the angle at which the multi-waveguide optical component may be coupled to the optical device.
