Grating products

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.

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
