The architectures investigated include fiber lasers, semiconductor lasers, and optical microcavities, with applications ranging from optical functions for sensing systems to optical communications, a field in which the department has established strong international recognition. The research activities are primarily experimental and cover topics ranging from fundamental studies, such as laser noise analysis and nonlinear optical phenomena, to very high-speed optical communication system demonstrations. In addition, several members of the department pursue more theoretical research based on analytical modeling approaches.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related Research Activities<\/h2>\n\n\n\n<div class=\"wp-block-query is-layout-flow wp-block-query-is-layout-flow\"><ul class=\"columns-3 wp-block-post-template is-layout-grid wp-container-core-post-template-is-layout-cda6dc4f wp-block-post-template-is-layout-grid\"><li class=\"wp-block-post post-9210 post type-post status-publish format-standard has-post-thumbnail hentry category-activites tag-communications tag-departement-sp tag-axe2 tag-lasers-applications-communications-optiques\">\n<figure style=\"aspect-ratio:4\/3;height:250px\" class=\"alignwide wp-block-post-featured-image\"><a href=\"https:\/\/www.institut-foton.eu\/en\/communications-optiques\/\" target=\"_self\"  style=\"height:250px\"><img loading=\"lazy\" decoding=\"async\" width=\"2560\" height=\"1707\" src=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/Photo2-pour-CO-scaled.jpg\" class=\"attachment-post-thumbnail size-post-thumbnail wp-post-image\" alt=\"Communications Optiques\" style=\"width:100%;height:100%;object-fit:cover;\" srcset=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/Photo2-pour-CO-scaled.jpg 2560w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/Photo2-pour-CO-300x200.jpg 300w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/Photo2-pour-CO-1024x683.jpg 1024w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/Photo2-pour-CO-768x512.jpg 768w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/Photo2-pour-CO-1536x1024.jpg 1536w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/Photo2-pour-CO-2048x1365.jpg 2048w\" sizes=\"auto, (max-width: 2560px) 100vw, 2560px\" \/><\/a><\/figure>\n\n<h3 class=\"wp-block-post-title\"><a href=\"https:\/\/www.institut-foton.eu\/en\/communications-optiques\/\" target=\"_self\" >Communications Optiques<\/a><\/h3>\n\n<div style=\"font-size:5px\" class=\"has-text-align-left wp-block-post-excerpt\"><p class=\"wp-block-post-excerpt__excerpt\">L\u2019Institut FOTON poss\u00e8de une forte expertise sur l\u2019\u00e9tude de composants et fonctions optiques d\u00e9di\u00e9s aux syst\u00e8mes de communications optiques \u00e0 tr\u00e8s haut d\u00e9bit.
