Abstract
Optical signal is the best suitable one for data processing and digital signal communication for its inherent parallelism and tremendous operational speed. Conventional electronic or optoelectronic devices are unable to fulfill this due to less speed and time delay. In the case of perfect electronic flip-flop, at the time of switching turned ON, there is noticeable propagation delay on the order of nanoseconds. In the case of an opto-electronic flip-flop, although the propagation delays time is much less than those of a pure electronic flip-flop about 10 to 100 times less, there are many disadvantages still have. Some of these disadvantages are delay of response time due to the use of spatial light modulators, an O/E converter that does not operate at all frequencies or wavelengths, and the unavailability of such materials. An optical input encoding methodology may be the alternative for the performance of two inputs all-optical flip-flop operations. These operations may be conducted in all-optical mode and will be parallel in nature. All the operations may be conducted with proper exploitation of some nonlinear materials. In this communication author reported an optical encoding technique for the construction of clocked J-K flip-flop with two inputs. All the operations are conducted by the proper exploitation of nonlinear materials.
