Abstract :
We present a 32/spl times/32 optical channel smart pixel array designed for use in an optical computing demonstrator system to numerically sort 1024 10-bit words. The system consists of two S-SEED on CMOS smart pixel arrays, an array of sorting nodes to compare pairs of words and a memory array to store data between comparisons and provide electrical I/O of data. Optical data communication between the devices is provided by differential optical beams using flip-chip bonded InGaAs MQW modulator and receiver arrays.
