Summary

This paper presents a laser-based micro alignment technique using an actor geometry to achieve sub-micron accuracy in fabricating highly precise 2D fiber collimator arrays. This method is crucial for applications in optical communication requiring parallel data transmission and overcomes limitations of standard manufacturing processes by allowing precise adjustment of fibers to micro lenses after assembly. Experimental results confirm the feasibility and principle behavior of the developed alignment method.
