A. We make volume phase holographic gratings (VPHGs) recorded interferometrically in DiChromated Gelatin (DCG) sealed in glass. There are many other optical recording media. DCG possesses the required combination of characteristics to produce very low polarization dependent loss (PDL), very high efficiencies, and wide bandwidths. These translate into benefits that enable telecom and other companies to leverage and capitalize on their own technologies.
