PING Telecom gratings

PING - Polarization Independent Gratings. 100% dielectric gratings offer unbeatable environmental and thermal stability combined with high-efficiency, low PDL performance.

PING Telecom gratings

Polarization independent (PING) telecom gratings from Ibsen are produced by holographic stepper technology in 100% dielectric materials. This leads to unbeatable thermal and environmental stability, with no polymers, epoxies, gelatins or metals in the optical path nor in the grating whatsoever. Advanced etching technology ensures highest diffraction efficiency and lowest PDL over a very broad bandwidth. Low angular sensitivity is an added bonus for module design and assembly.
