We demonstrate a scalable and reconfigurable optical directed-logic architecture consisting of a regular array of integrated optical switches based on microring resonators. The switches are controlled by electrical input logic signals through embedded p-i-n junctions. The circuit can be reconfigured to perform any combinational logic operation by thermally tuning the operation modes of the switches. Here we show experimentally a directed logic circuit based on a 2×2 array of switches. The circuit is reconfigured to perform arbitrary two-input logic functions.
