Abstract

An optoelectronic smart pixel device for optically reconfigurable Boolean logic gate array is proposed. It consists of more than 4 X 10⁵ pixels used as logic gates that can operate in parallel. By setting different optical biases on pixels, every pixel is reconfigurable (to perform different kinds of logic gate operations). All kinds of logic gates can be implemented simultaneously in this device. The principle of operation and its fundamental characteristics are described in detail. The device makes fully use of the physics features of amorphous silicon photoconductor and liquid crystal and does not need the controlling architecture with very large scale integration circuits. Therefore, bigger aperture ratio, higher resolution (more than 45 lines/mm), and higher space bandwidth product are achievable.
