Abstract
This disclosure describes a system and method for providing a 2D collimator array with reduced back reflection. The collimator array comprises a pair of angled glass plates between a lens array and a fiber array. The lens array and the fiber array each comprise a plurality of angled holes.
Claims14
A 2D collimator array system, comprising:
- a fiber array comprising a plurality of holes, wherein each hole of the plurality of holes is:
- configured to receive an optical fiber, and
- angled relative to a normal of the fiber array to reduce back reflection;
- a lens array positioned parallel to the fiber array, wherein the lens array comprises a plurality of lenses aligned with the plurality of holes;
- and
- a pair of angled glass plates disposed between the fiber array and the lens array, wherein the angled glass plates are configured to compensate for beam distortion caused by the plurality of holes of the fiber array.
