Phase masks are the production tool used to write gratings in fibers and waveguides. Ibsen Phase masks incorporate unbeatable, interferometric (holographic) patterning technology into a production friendly Phase mask.
– for easy and cost-effective fabrication of Bragg gratings
Ibsen’s +1/-1 order principle Phase masks ensure quality and facilitate production in the telecommunications, sensor and laser industries. In the production of fiber and waveguide Bragg gratings, the Phase mask is illuminated by a high-power UV laser, typically an excimer laser or frequency-doubled gas laser. Self-interference between the diffracted orders produces the required pitch in the fiber or waveguide.
