By a News Reporter-Staff News Editor at Computers, Networks & Communications -- Investigators publish new report on Photonics. According to news reporting originating in Beijing, People’s Republic of China, by VerticalNews journalists, research stated, “Linear-optical logic gates have the potential to be the bases of the next-generation information technology (IT) because of the low power consumption and rapid response. This study proposes a general theoretical model to obtain the optimal solutions for linear-optical logic gates.”
Funders for this research include Ministry of Science and Technology of the People’s Republic of China, National Natural Science Foundation of China.
The news reporters obtained a quote from the research from Peking University, “All common logic gates (AND, OR, NOT, NAND, NOR, XOR, and XNOR) are experimentally demonstrated with one single sample structure based on ultracompact plasmonic waveguides. The measured intensity contrast ratio between the output-logic ‘1’ and ‘0’ states reaches 28 dB for the OR gate and 9.4 dB for the AND gate, thereby approaching the theoretical maximum of infinity and 9.5 dB, respectively. The proposed logic gates provide uniform output intensities for identical output logics when the input logics are different. The measured intensity discrepancies are below 1% for the three output-logic ‘1’ states of the OR gate and the three output-logic ‘0’ states of the AND gate. This phenomenon is favored in practical applications and the cascading of logic gates.”
According to the news reporters, the research concluded: “The proposed universal linear-optical logic gate with maximal intensity contrast ratios may find important future applications in the field of IT.”
