Optical response of thin supported palladium films to hydrogen: Non-destructive testing for hydrogen detection
(1999)The properties of thin palladium films on silicon dioxide/silicon substrates are investigated. As the electrical properties of very thin palladium films cannot be measured, due to highly discontinuous nature of the films ...

Phase shifted Bragg gratings formed in optical fibres by post-fabrication thermal processing
(1996)Fibre Bragg gratings have been post-fabrication processed using localised heat treatment, with significant changes to their transmission and reflection characteristics being observed. Experimental results of the spectral ...

Superimposed multiple Bragg gratings
(1994)The authors demonstrate the inscription of seven Bragg gratings at the same location on a photosensitive fibre. These superimposed Bragg gratings were written over a 60nm span in the region of 1530nm with reflectivities ...
