Abstract
Thin films of V02 are capable of reversibly switching from a transparent to a metal state at high speeds and with high spatial resolution. The result is a dynamic reticle or mask in the IR with large on-off ratios for both reflection and transmission. Three applications for which V02 films are a key will be discussed: a high performance real time coherent optical data processor, a transmit/receive switch and a fast random access scan laser with a large field of view and high resolution.
