"Logic selfelectrooptic effect devices: quantumwell optoelectronic multiplexers,
and shift registers" IEEE J. of Quantum Electronics, 28, 15391553 (1992). Twodimensional
arrays of logic selfelectrooptic effect devices (LSEEDs), consisting of electrically
connected quantumwell pin diode detectors and modulators are demonstrated. The topology
of the electrical connections between the detectors is equivalent to the connections
between transistors in CMOS circuits. Three different LSEED arrays were built and tested.
Each element in one array can implement any of the four basic Boolean logic functions
(i.e., NOR, NAND, AND, OR). Each element in the second LSEED array can implement the
function E=AB+CD. The third LSEED array consists of 32*16 arrays of symmetric SEEDs
(SSEEDs) connected with optoelectronic transmission gates. Photonic switching nodes,
multiplexers, demultiplexers, and shift registers have been demonstrated using this array
