Paper Abstract

A light valve is a key component for optical signal processing. A liquid crystal layer is activated by light due to a proximate photoconducting layer. Contemporary commercial light valves are made with an amorphous silicon photoconducting layer which offers an impedance change between light and dark states of up to three orders of magnitude. One drawback of using amorphous silicon is that the resolution of the valve is limited by lateral photocharge spreading. We hope to overcome this by using thin organic photoconducting layers.
