This project involves the design and simulation of a smart-pixel arrangement capable of compensating the interconnect losses of two analog optical signals based on its positional coordinates in the waveguide array and a programmable attenuation factor, before comparing them to produce a digital output. This pixel has been incorporated into an optical co-processor system to rank an array of analog optical signals, with an operation time almost independent of the number of inputs.
