PING – polarization independent gratings

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

Benefits

  • High efficiency, low PDL, broad spectral bandwidth

  • Transmission gratings give great alignment tolerances

  • Low transmitted wavefront distortion

  • High tolerance to illumination angle of incidence

  • 2-grating designs are possible, offering compact design possibilities

  • Unbeatable thermal & environmental stability & lifetime

Applications

  • Wavelength Selective Switches (WSS) / ROADMS

  • Tunable filters

  • Optical channel monitors (OCM)

  • Wavelength blockers

  • Mux / Demux

  • LIDAR

  • OCT (Optical Coherence Tomography)

Product overview

While we primarily supply PING gratings as OEM gratings, the following gratings, and many other gratings, are available from stock. You can order the gratings via the product links, or request a quotion for these or other customized gratings below.

Polarization Independent 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 the highest diffraction efficiency and lowest PDL over a very broad bandwidth. Low angular sensitivity is an added bonus for module design and assembly.
