The most demanding features of a tapered (lensed) fiber array (FA) are the uniform beam direction and lens concentricity.
Tapered fiber arrays are limited by commercial fiber's intrinsic accuracy. The silicon-on-silicon structured tapered FA shows stable performance even in hostile environment. The AR coated fiber array can be metallized for the application requiring high hermeticity
