Product: Transmission Diffraction Gratings for Optical Communications

Transmission gratings operate to angularly disperse incident light into a spectrum. LightSmyth’s transmission gratings utilize state-of-the-art design and precise lithographic wafer-scale fabrication to deliver record-breaking optical performance combined with low cost, providing your optical systems with a powerful competitive edge. These gratings provide the world’s best combination of highest diffraction efficiency, low PDL and highly competitive pricing.

Measured Diffraction Efficiency Curves

Advantages:

  • Exceptional diffraction efficiency
  • Ultra-low polarization-dependent loss
  • Special design for broad passband and low angular sensitivity
  • Uses only fused silica and highly robust dielectric materials
  • No polymers or organics are used; Telcordia-qualified
  • Each grating is a master; ultra-low scatter
  • Extremely precise line density (line density uniformity <0.001 lines/mm)
  • Highly competitive pricing

Applications:

  • Optical telecommunications (ROADM, WSS, WDM MUX/DEMUX)
  • Pulse compression of pico- and femto-second pulses
  • High power lasers
  • Spectral beam combining
  • Remote optical sensors and spectroscopy

Specifications below are for stock gratings that are available immediately. Transmission gratings of similar performance with other line densities, operating spectral bands, input/output beam geometries and substrate sizes can be supplied.
