Polarization Independent Gratings PING
PING - Polarization Independent Gratings Telecom Transmission Gratings, 966 lines/mm
100% dielectric gratings offer unbeatable environmental and thermal stability combined with high-efficiency, low PDL performance.
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 diffrection efficiency and lowest PDL over a very broad bandwidth. Low angular sensitivity is an added bonus for module design and assembly.
