The concepts of a THz communication system will be given on generation, modulation, beam control\/handling, detection (direct or sub-harmonic mixing, analysis), with special focus on the use of optically-driven sources as THz transmitters. An overview of the actual challenges in the topic will be presented and discussed.

The double-metal patch antenna structure is able to both confine photons in a highly subwavelength volume and gather radiation from a very large cross section. The focus will go on the recent application of double-metal patch antenna resonators in the THz and mid-IR spectral regions, where they have allowed a substantial increase in the temperature performance of quantum detectors.<\/p>\n<p><b>Practical (optional):<\/b><\/p>\n<p>The participants will perform reflectivity measurements on patch antenna arrays using a Fourier transform IR (FTIR) spectrometer, and if time permits, photocurrent measurements.<\/p>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-rid7kd-5ac2f0a65e22464f0626eb4a7afd4589\">\n#top .hr.av-rid7kd-5ac2f0a65e22464f0626eb4a7afd4589{\nmargin-top:0px;\nmargin-bottom:0px;\n}\n.hr.av-rid7kd-5ac2f0a65e22464f0626eb4a7afd4589 .hr-inner{\nwidth:20px;\n}\n<\/style>\n<div  class='hr av-rid7kd-5ac2f0a65e22464f0626eb4a7afd4589 hr-custom  avia-builder-el-17  el_after_av_hr  avia-builder-el-last  hr-left hr-icon-no'><span class='hr-inner inner-border-av-border-none'><span class=\"hr-inner-style\"><\/span><\/span><\/div>\n<\/div><\/div><\/div><\/li>\n<\/ul><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":63,"menu_order":5,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-36173","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/pages\/36173","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/types\/page"}],"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=36173"}],"version-history":[{"count":0,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/pages\/36173\/revisions"}],"up":[{"embeddable":true,"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/pages\/63"}],"wp:attachment":[{"href":"https:\/\/www.iemn.fr\/en\/wp-json\/wp\/v2\/media?parent=36173"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
