Abstract : We have evaluated nonlinear interface optical switches (NIOS) based on thin films of laser deposited metal oxide clusters. Films having nominal thickness 200nm and ranging in stoichiometry from WO2.6 to WO2.5, were evaluated in at least two configurations. Wanting to understand the considerable optical nonlinearity exhibited by these laser deposited group VI metal oxide cluster films, time resolved and other Raman experiments were conducted using WO3 powder. In addition to helping explain the results of the NIOS testing, these and subsequent experiments revealed a phenemenon with considerable potential for optical switch, memory and other optical computing applications. Using this phenomenon, we conclude by discussing the viability of optical memory systems using the new media.
