We report the first demonstration of autocatalysis and oscillatory behaviour in the solid-state where no decomposition process is involved. Our material system is solid-state silica glass impregnated with hydrogen. It is at the heart of photosensitivity in glass-based optical waveguides and devices, which have many applications including telecommunication devices, fibre lasers, and optical sensors. Consequently, the results reported here extend the engineering of chemical complexity to a previously uncharted area in materials science of particular relevance to photonic applications. Diagnosis is carried out optically, opening up a new approach to characterisation of such catalytic processes generally.
