Photo-Regulated Reconfigurable Arithmetic Circuits Using Physically Transient Diffractive Optics

In this paper we report a kind of physically transient diffractive optical elements (DOEs) for inducing photo-regulated reconfigurable arithmetic circuits. The silk-based DOE, known for its controllable degradation, strong mechanical strength and high transmittance, can easily regulate the luminous intensity and distribution of diffractive light spots applied to tune the property of the photoresistors. By precisely controlling the property of the silk-based DOE, the resistances of the photoresistors can be regulated according to the pre-design, which provides a novel way for realizing kinds of reconfigurable arithmetic circuits.
