Realization of all-optical frequency-encoded dibit-based OR and NOR logic gates with simulated verification

摘要

Optics is recognized as a powerful and prospective candidate for the realization of logic devices, digital optical systems for communication, and computation due to its super-fast speed. Alloptical frequency-encoded dibit representation techniques conduct real-time operations with ultra high switching speed rather than all conventional opto-electronic and optical switches. So, a high degree of parallelism can be exploited from these proposed systems. Here, the authors have proposed all-optical frequency-encoded dibit-based OR and NOR logic gates using the optical switches like reflected semiconductor optical amplifiers and add/drop multiplexers.
