Contactless Optical Packaging Concept for Laser to Fiber Coupling

“…In comparison to other assembly methods such as adhesive bonding and gluing, laser welding offers better advantages in terms of precision, strength, and long-term stability. However as an alternative, in [22], a multi-fiber array fixation using UV-curing with reproducibility of ±40 nm has been demonstrated. By varying the fibersubstrate distance, the authors have achieved a repeatable vertical shrinkage in the range of 100-220 nm.…”
