Abstract
Broad-band, dynamic (switchable), solid-state, ultrafast (sub-ns) optical shutter activated by a laser or other high intensity radiation source is provided based on novel interfaces of inorganic semiconductor (SC) electrodes with conducting polymers (CPs). The CPs, normally switched electrochemically between opaque and transparent states, are switched via direct charge transfer from photoexcitation of the SC by a laser or other high intensity radiation source. The SC thus provides both trigger and energy for polymer switching. Preliminary data for SC/CP switching shows sub-ns risetimes and falltimes in the tens of ns, with large OD changes (ca. 2.0 at 532 nm).
