摘要: An optical fiber assembly is provided including an optical fiber and a beam shaping component affixed to an extremity of the optical fiber. The optical fiber supports a guided mode having a spatial profile defining a first shape. The beam shaping component defines a light path and has a transversal refractive index profile including an outer refractive index value greater than an inner refractive index value. The beam shaping component transforms the spatial profile of a light beam propagating along the light path between the first shape and a second shape different from the first shape. The optical assembly may for example transform a Gaussian light beam into a flat-top or donut shape.
