However, the ongoing massive deployment of 5G networks has unveiled inherent limitations that have stimulated the demand for innovative technologies with a vision towards 6G communications. Terahertz (0.1-10 THz) technology is identified as a critical enabler for 6G. Especially, the 300 GHz band is deeply investigated.<\/p>\n<blockquote>\n<p><a href=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2023\/04\/phototunable.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-57296\" src=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2023\/04\/phototunable.jpg\" alt=\"\" width=\"250\" height=\"212\" srcset=\"https:\/\/www.iemn.fr\/wp-content\/uploads\/2023\/04\/phototunable.jpg 282w, https:\/\/www.iemn.fr\/wp-content\/uploads\/2023\/04\/phototunable-14x12.jpg 14w\" sizes=\"auto, (max-width: 250px) 100vw, 250px\" \/><\/a>A new class of phototunable devices, using on-chip topological terahertz devices consisting of a broadband single-channel 160 Gbit\/s communication link and a silicon Valley Photonic Crystal based demultiplexer has been demonstrated. As a proof of concept, the demultiplexing of high spectral efficiency 40 Gbit\/s signals and real-time streaming of uncompressed high-definition (HD) video (1.5 Gbit\/s) using the topological photonic chip, including an optical control has been reached, paving the way to optically controlled THz channels manipulation.<\/p>\n<\/blockquote>\n<p><em>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-wzsvks-2a4e30804f9db3ceeeeb0ecf79e8d718\">\n.av_font_icon.av-wzsvks-2a4e30804f9db3ceeeeb0ecf79e8d718{\ncolor:#7bb0e7;\nborder-color:#7bb0e7;\n}\n.av_font_icon.av-wzsvks-2a4e30804f9db3ceeeeb0ecf79e8d718 .av-icon-char{\nfont-size:25px;\nline-height:25px;\n}\n<\/style>\n<span  class='av_font_icon av-wzsvks-2a4e30804f9db3ceeeeb0ecf79e8d718 avia_animate_when_visible av-icon-style- avia-icon-pos-left avia-icon-animate'><span class='av-icon-char' aria-hidden='true' data-av_icon='\ue826' data-av_iconfont='entypo-fontello' ><\/span><\/span>Phototunable chip-scale topological photonics : 160 Gbps waveguide and demultiplexer for THz 6G communication Nat Commun 13, 5404 (2022). <\/em><a href=\"https:\/\/www.nature.com\/articles\/s41467-022-32909-6\" target=\"_blank\" rel=\"noopener\"><em>https:\/\/www.nature.com\/articles\/s41467-022-32909-6<\/em><\/a><\/p>\n<div  class='avia-button-wrap av-rpqvoq-0af67a3668ea5c49188032a6f5786cb7-wrap avia-button-left  avia-builder-el-3  el_after_av_font_icon  avia-builder-el-last'><a href='mailto:guillaume.ducournau@iemn.fr'  class='avia-button av-rpqvoq-0af67a3668ea5c49188032a6f5786cb7 av-link-btn avia-icon_select-yes-left-icon avia-size-small avia-position-left avia-color-silver'   aria-label=\"guillaume.ducournau@iemn.fr\"><span class='avia_button_icon avia_button_icon_left' aria-hidden='true' data-av_icon='\ue805' data-av_iconfont='entypo-fontello'><\/span><span class='avia_iconbox_title' >guillaume.ducournau@iemn.fr<\/span><\/a><\/div>\n<\/div><\/section><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[297],"tags":[],"class_list":["post-57301","post","type-post","status-publish","format-standard","hentry","category-newsletter"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/57301","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/comments?post=57301"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/posts\/57301\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=57301"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/categories?post=57301"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/tags?post=57301"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
