Abstract: An optical waveguide device comprising a core structure formed of deuterated amorphous carbon. The optical waveguide device decreases losses due to hydrogen absorption. A process for making the optical waveguide device is also disclosed.

Abstract: The present disclosure relates to a limited play optical storage media and a method for limiting access to data thereon. This storage media comprises: an optically transparent substrate; a reflective layer; an oxygen penetrable UV coating disposed on a side of the substrate opposite the reflective layer; and a reactive layer disposed between the UV coating and the substrate, the optical storage media having an initial percent reflectivity of about 50% or greater and a subsequent percent reflectivity of about 45% or less.
