In the recent past, optics has been renowned as a powerful and potential candidate for implementation of logic gates, devices, optical computers, and communication for the benefit of speed of information processing. For the operation of a frequency encoded data processing system, optical logic gates based on the principle of frequency conversion of some nonlinear materials play the main role. Some papers have discussed the advantage of accuracy of dibit logic by implementing logic operations on dibit representation techniques, which provides the advantage of high-speed operation and reduces the bit error problem. Here, exploiting this phenomenon, frequency encoded all-optical dibit-based NAND and NOR logic gates using optical switches such as reflective semiconductor optical amplifiers and add/drop multiplexers with appropriate dibit checking facility are proposed by the authors. Also the authors have verified the operations through proper simulation using MATLAB (R2008a).
