abstract:Diode logic (DL) or diode-resistor logic constructs Boolean logic gates from diodes acting as electrically operated switches. While diode logic has the advantage of simplicity, the lack of an amplifying stage in each gate limits its application.
Multiple-valuedopticallogic implementation have firstly been demonstrated by usingbistablelaserdiode (BILD) or bistable light emittingdiode (BILED) circuits.
