Research output: Chapter in Book/Report/Conference proceedingConference contribution


As-deposited and derivatized WO3-x films of various stoichiometry were examined in a `nonlinear interface' configuration. The optical properties of the films at 632 nm were modulated using 850 nm and 488 nm CW lasers either separately or simultaneously, Some films were modified by electrochemical reduction. Purely photoinduced changes were interpreted in the context of photoinduced chemistry involving water and/or oxygen exchange with the ambient atmosphere. Both reversible and irreversible changes were observed. Applications as either all-optical switches or logic devices are discussed.
