The serially inserted DI, on the other hand, adds a phase difference to the direct and delayed copies of the incoming switched signal. This in turn further enhances the switching performance and speed of the formed logic gates. <\/p>\n<p>The researchers calculated and compared the quality factor (Q-factor) and cross-correlation coefficient (XC) of QDSOAs-TS-MZIs-DI and the conventional MZIs with QDSOAs (QDSOAs-MZIs) to evaluate the performance of the two considered logic gates at 1 Tb\/s.<\/p>\n<p>The comparison reveals that the QDSOAs-TS-MZIs-DI outperforms the other two alternatives (QDSOAs-TS-MZIs and QDSOAs-MZIs), implying that it should be used as a switching module for ultrahigh-speed Boolean logic functions. <\/p>\n<p>The study was published in <i>Pramana<\/i>. It is expected to shed light on the design of future integrated logic circuits at high speeds and with better performance.\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            <a rel=\"nofollow noopener\" target=\"_blank\" class=\"text-medium text-info mt-2 d-inline-block\" href=\"https:\/\/phys.org\/news\/2022-05-reconfiguration-magnetic-skyrmions-based-logic-gates.html\">Implementation and reconfiguration of magnetic skyrmions-based logic gates in one single nanotrack<\/a>\n                                        <\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                AMER KOTB et al, Numerical demonstration of NAND and XNOR Boolean functions using quantum-dot semiconductor optical amplifiers-based turbo-switched Mach\u2013Zehnder interferometers and delayed interferometer at 1 Tb\/s, <i>Pramana<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1007\/s12043-022-02329-8\">DOI: 10.1007\/s12043-022-02329-8<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Chinese Academy of Sciences<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"https:\/\/english.cas.cn\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/techx.b-cdn.net\/tmpl\/v2\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 Novel scheme for logic operations running at 1 Tb\/s (2022, May 27)<br \/>\n                                                 retrieved 28 May 2022<br \/>\n                                                 from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-05-scheme-logic-tbs.html<\/p>\n<p>                                            This document is subject to copyright.
