Abstract: A method for selection and calculation of the parameters of axisymmetric and anamorphic graded-index lenses for optical matching devices is developed and tested. These devices are intended for detachable connectors joining single-mode fibers to strip optical waveguides and are characterized by a greater tolerance to a mismatch between these waveguides. An experimental study is reported of a prototype of an optical matching device based on graded-index lenses characterized by insertion losses from 1–3 dB.
