The NORIA tool is a manufacturing tool to produce

Fiber Bragg Gratings (FBGs). A Deep Ultra Violet laser

(Coherent Excistar XS 500Hz—ArF) and a phase

mask (Ibsen Photonics) are used to transfer a periodic

pattern into the core of a photosensitive optical

fiber.

The NORIA tool holds a number of different masks in

a revolver like holder, each mask having a different

pattern periodicity. This flexibility allows the end-user

to manufacture FBGs from predefined recipes in an

automated fashion.

In addition, multiple FBGs in an array can be written

along the fiber at any desired position using the

NORIA tools accurate positioning stage.
