Lensed Fiber Array Unit(LFAU) PDF

The Lensed Fiber Array Unit (LFAU) is a fiber optic lens array module constructed by utilizing a V-Groove substrate to mount one or multiple lensed fibers at specified intervals. The LFAU comprises components such as a V-Groove substrate, lensed fibers, a cover plate, and adhesive. It is designed to achieve precise alignment and efficient coupling with silicon photonic chips and waveguides.

Features : -High coupling efficiency -Waveguide coupling -Easy to assemble -Low cost

Applications: -Silicon photonics -Chip coupling
