Telecom gratings
Ibsen gratings for telecom. When efficiency matters
Ibsen’s telecom gratings are advanced, polarization-independent (PING) gratings fabricated using advanced lithographic or holographic stepper patterning combined with reactive ion etching in 100% dielectric materials. This technology provides unmatched thermal and environmental stability, with no polymers, epoxies, gelatins, or metals in the optical path – or anywhere in the grating structure.
The precision of our etching technology delivers industry-leading diffraction efficiency and ultra-low polarization-dependent loss (PDL) across an exceptionally broad bandwidth. Additionally, the low angular sensitivity of our gratings simplifies module design and facilitates seamless integration.
Key benefits
Dual-polarization PING gratings are unmatched when efficiency matters. While this is critical in telecom applications, many other fields also benefit from their exceptional dual-polarization performance. Below is a list of key application areas for PING gratings, both within and beyond telecommunications.
