Abstract

A radiation-controlled switch (6) includes an optically active material (12), which is preferably a 1000 ANGSTROM thick VO2 layer on a substrate (10), the optically active material having electrically mutually isolated contacts (14, 16) formed thereon, and being associated with a radiation source (8), which may be a laser, directing electromagnetic radiation at the optically active material wherein on incidence of the radiation from the source, at least part of the optically active material undergoes a phase change from a non- metallic to a metallic phase and establishes electrical contact between at least two of the contacts. Other optically active materials used are NbO2, Fe3O4, NiS, FeS, V2O3, V8O15 or MoTe2. <IMAGE>
