Abstract

Optical fibers with cores made of germanosilicate, phosphosilicate, and nitrosilicate glasses are loaded by molecular hydrogen at a pressure of 10 MPa and room temperature. Then, preloaded fibers are kept in a hydrogen atmosphere at the same pressure and various fixed temperatures up to 700°C and the transmission spectra of the fibers are measured in situ at a constant temperature with equal time intervals. The kinetics of the chemical interaction between hydrogen and the silica is determined by analyzing an increase in the optical absorption at the overtones of OH and NH groups.
