| Abstract: | The optical characteristics of GRIN lens are analyzed by applying principles of the rayoptics. A mathematical model used to compute losses of GRIN lens. off-axis coupling has been carriedout. We show the relative curve between losses and offset distance, and provide a theoretical referenceto design GRIN's off-axis coupling. |
