Optical logic gates are most important factors for the parallel operations and utilizations in VLSI circuits for the very high speed data processing and communications. This calls for multivalued logic implementation. In this paper we have communicated the trinary optical logic gates with optical implementations and a few applications of it to the half adder and full adder circuits, this may also be extended to multiplexers and de-multiplexers, flip-flops, registers, counters, etc. © Springer Science+Business Media B.V. 2008.

Modified Ternary Optical Logic Gates and their Applications in Optical Computation

Innovations and Advanced Techniques in Systems, Computing Sciences and Software Engineering

With the demanding scenario of communication and optical computing technology the trinary and quadruple valued logic systems are the most important ones in the many valued logic system. Different techniques are being proposed day-by-day to implement the multi-valued logics (MVL). In our previous papers we have proposed the modified trinary number (MTN) systems using savart plates and spatial light modulators (SLM). In this paper we have communicated the quadruple valued logic system using di-bit concept and their implementations to meet up the tremendous needs of speeds by exploiting the advantages of savart plates and spatial light modulators (SLM) in the optical tree architecture (OTA). © Springer Science+Business Media LLC 2012.

Quadruple-valued logic system using savart plate and spatial light modulator (SLM) and it's applications

With the demand of the super fast processing and handling of huge volume of data the scientific workers in the field of computer and optics felt the importance of optical computation with multivalued logic. One of the most important number system suitable for optical computation with multivalued logic is the modified trinary number (MTN) system because of its carry and borrow-free operations. At this juncture to avail the advantages of both the Binary and MTN system the conversion from one system to another is most important. In this paper we have communicated the conversion from Binary to MTN and vice-versa including the mixed MTN with details of optoelectronic circuit implementation. © 2009 Springer Science+Business Media B.V.
