Hydrogen loading of optical waveguides by use of host diluent gases.
Recent dramatic improvements in photosensitivity gas mixtures when very low hydrogen concentrations (as low as 0.1%) were used are shown to involve condensation of the host gas. The vapor pressure of the host determines the effective partial pressure of the hydrogen, and this accounts for the bulk of the observed enhancements.
