Intro to Transmission VPH Gratings

Introduction to Telecommunication Grating Products

Kaiser's UltraSpec™ family of products are based on our volume phase holographic (VPH) grating technology

All our UltraSpec™ products  share the following properties

  • High dispersion
  • Low polarization dependent loss (PDL)
  • Low insertion loss
  • Convenient packaging

In addition, UltraSpec™ gratings are not affected by mechanical damage or exposure to temperature and humidity. Our UltraSpec™ gratings can be configurable to all levels of Telcordia GR-1221 requirements (e.g. CO, UNC, hermetic, non-hermetic).

Unlike traditional surface relief grating technologies no special handling is needed making these modules easy to install (increasing manufacturing yield), support (minimize life-cycle costs), and replace.  If these devices ever get dirty then they can be wiped clean! - the VPH robustness advantage!
