It could launch the next generation of ultra-fast devices for exchanging massive amounts of data, with applications in 6G communications and beyond, the institution announced in a <a href=\"https:\/\/actu.epfl.ch\/news\/electronic-metadevices-break-barriers-to-ultra-fas\/\">press release<\/a>.<\/p>\n\n\n\n<p>Until now, the ability to make electronic devices faster has come down to a simple principle: scaling down transistors and other components. But this approach is reaching its limit, as the benefits of shrinking are counterbalanced by detrimental effects like resistance and decreased output power.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">More information, smaller devices<\/h2>\n\n\n\n<p>Elison Matioli of the Power and Wide-band-gap Electronics Research Lab (POWERlab) in EPFL\u2019s School of Engineering explains that further miniaturization is therefore not a viable solution to better electronics performance. <\/p>\n\n\n\n<p>\u201cNew papers come out describing smaller and smaller devices, but in the case of materials made from gallium nitride, the best devices in terms of frequency were already published a few years back,\u201d he says. \u201cAfter that, there is really nothing better, because as device size is reduced, we face fundamental limitations. This is true regardless of the material used.\u201d<\/p>\n\n\n\n<p>In response to this challenge, Matioli and PhD student Mohammad Samizadeh Nikoo came up with a new approach to electronics that could overcome these limitations and enable a new class of terahertz devices. Instead of shrinking their device, they rearranged it, notably by etching patterned contacts called metastructures at sub-wavelength distances onto a semiconductor made of gallium nitride and indium gallium nitride. These metastructures allow the electrical fields inside the device to be controlled, yielding extraordinary properties that do not occur in nature.<\/p>\n\n\n<div class=\"vlp-link-container vlp-layout-basic wp-block-visual-link-preview-link\"><a href=\"https:\/\/ioplus.nl\/archive\/en\/selected\/photonic-filter-enables-next-generation-mobile-network-6g\/\" class=\"vlp-link\" title=\"Photonic filter enables next-generation mobile network (6G)\"><\/a><div class=\"vlp-layout-zone-side\"><div class=\"vlp-block-2 vlp-link-image\"><\/div><\/div><div class=\"vlp-layout-zone-main\"><div class=\"vlp-block-0 vlp-link-title\">Photonic filter enables next-generation mobile network (6G)<\/div><div class=\"vlp-block-1 vlp-link-summary\">Researchers at the University of Twente have developed a revolutionary programmable integrated microwave photonic filter.<\/div><\/div><\/div>\n\n\n<h2 class=\"wp-block-heading\">6G and beyond<\/h2>\n\n\n\n<p>As Samizadeh Nikoo explains, modulating terahertz waves is crucial for the future of telecommunications, as the increasing data requirements of technologies like autonomous vehicles and 6G mobile communications are fast reaching the limits of today\u2019s devices. <\/p>\n\n\n\n<p>The electronic metadevices developed in the POWERlab could form the basis for integrated terahertz electronics by producing compact, high-frequency chips that can already be used with smartphones, for example.<\/p>\n\n\n\n<p>\u201cThis new technology could change the future of ultra-high-speed communications, as it is compatible with existing processes in semiconductor manufacturing. We have demonstrated data transmission of up to 100 gigabits per second at terahertz frequencies, which is already 10 times higher than what we have today with 5G,\u201d Samizadeh Nikoo says.<\/p>\n","protected":false},"author":2583,"featured_media":515802,"template":"views\/single-selected.blade.php","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[8553],"tags":[42670,33486,8192,129620,39636,129622],"location":[52892],"internal_archives":[],"class_list":["post-437414","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-digital","tag-6g-en","tag-communications","tag-data-en","tag-electromagnetic-frequencies","tag-epfl-en","tag-metadevices","location-switzerland"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/12\/processor-g85de6d31a_1920.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/francesco-morelli\/","display_name":"Francesco Morelli"},"relative_dates":{"created":"Posted 3 years ago","modified":"Updated 3 years ago"},"absolute_dates":{"created":"Posted on February 20, 2023","modified":"Updated on February 20, 2023"},"absolute_dates_time":{"created":"Posted on February 20, 2023 1:00 pm","modified":"Updated on February 20, 2023 1:00 pm"},"featured_img_caption":"","tax_additional":{"category":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/en\/category\/digital\/\" class=\"advgb-post-tax-term\">Digital<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">Digital<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/6g-en\/\" class=\"advgb-post-tax-term\">6G<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/communications\/\" class=\"advgb-post-tax-term\">communications<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/data-en\/\" class=\"advgb-post-tax-term\">data<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/electromagnetic-frequencies\/\" class=\"advgb-post-tax-term\">electromagnetic frequencies<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/epfl-en\/\" class=\"advgb-post-tax-term\">EPFL<\/a>","<a href=\"https:\/\/ioplus.nl\/archive\/en\/tag\/metadevices\/\" class=\"advgb-post-tax-term\">Metadevices<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">6G<\/span>","<span class=\"advgb-post-tax-term\">communications<\/span>","<span class=\"advgb-post-tax-term\">data<\/span>","<span class=\"advgb-post-tax-term\">electromagnetic frequencies<\/span>","<span class=\"advgb-post-tax-term\">EPFL<\/span>","<span class=\"advgb-post-tax-term\">Metadevices<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/en\/\" class=\"advgb-post-tax-term\">EN<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/?taxonomy=post_translations&#038;term=pll_63f3509c37444\" class=\"advgb-post-tax-term\">pll_63f3509c37444<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">pll_63f3509c37444<\/span>"],"slug":"post_translations","name":""},"location":{"linked":["<a href=\"https:\/\/ioplus.nl\/archive\/location\/switzerland\/\" class=\"advgb-post-tax-term\">Switzerland<\/a>"],"unlinked":["<span class=\"advgb-post-tax-term\">Switzerland<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/437414","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2583"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/515802"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=437414"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=437414"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=437414"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=437414"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=437414"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
