The self-assembly of molecularly precise nanostructures is widely expected to form the basis of future high-speed integrated circuits, but the technologies suitable for such circuits are not well understood. In this work, DNA self-assembly is used to create molecular logic circuits that can selectively identify specific biomolecules in solution by encoding the optical response of near-field cou...

optimization techniques are discussed using digital logic network using threshold logic. Almost same energy consumption changing speedup is possible using threshold network and many complex functions can be implemented using threshold logic with lesser number of logic gate and logic level for which these optimization techniques becomes popular for digital system design and applications. In this...

The optical ZCZ code, which is a set of pairs of binary and bi-phase sequences with zero correlation zone, can provide optical code division multiple access (CDMA) communication system without co-channel interference. We proposed the compact construction of a code generator and a bank of matched filters for this code. This paper gives and evaluates an optical ZCZ-CDMA wireless communication sys...

This paper provides the mathematical derivation of the equivalent logic gates for spike code processing in neurons. It derives the computational equivalence between the binary code and spike code to illustrate the correspondence between binary and spike code logic operations theoretically. It identifies the similarities and differences between biological neural processing and binary logic gate ...

We demonstrate the unambiguous entangling operation of a photonic quantum-logic gate driven by an ultrabright solid-state single-photon source. Indistinguishable single photons emitted by a single semiconductor quantum dot in a micropillar optical cavity are used as target and control qubits. For a source brightness of 0.56 photons per pulse, the measured truth table has an overlap with the ide...

The realization of all-optical integration and optical computing has always been our goal. One the most significant challenges is to make integrated logic devices as small possible. Here, we report implementation ultracompact chips on silicon photonic platforms by topology optimization. footprint for fabricated gates with XOR OR functions only 1.3 × μm2 (∼0.84λ 0.84λ) that are smallest dielectr...
