These waveguides, typically only a few centimetres long and featuring a small effective mode area, provide efficient nonlinear interactions. In addition, integrated chalcogenide glass ring micro-resonators have been used to enhance the nonlinear optical effects within the cavity, leading to a significant improvement in conversion efficiency. <\/li>\n\n\n\n<li>Guided mid-infrared luminescence in rare-earth-doped chalcogenide glasses integrated into photonic devices, demonstrating the potential of these materials for integrated mid-infrared light sources.<\/li>\n<\/ul>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-7387b849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"462\" height=\"355\" src=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-54.png\" alt=\"\" class=\"wp-image-9196\" srcset=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-54.png 462w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-54-300x231.png 300w\" sizes=\"auto, (max-width: 462px) 100vw, 462px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"496\" height=\"362\" src=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-55.png\" alt=\"\" class=\"wp-image-9197\" srcset=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-55.png 496w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-55-300x219.png 300w\" sizes=\"auto, (max-width: 496px) 100vw, 496px\" \/><figcaption class=\"wp-element-caption\">Demonstration of self-phase modulation (SPM) and four-wave mixing (FWM) in integrated chalcogenide glass waveguides exhibiting third-order nonlinear optical properties.<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"515\" height=\"359\" src=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-56.png\" alt=\"\" class=\"wp-image-9198\" srcset=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-56.png 515w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-56-300x209.png 300w\" sizes=\"auto, (max-width: 515px) 100vw, 515px\" \/><figcaption class=\"wp-element-caption\">Enhancement of nonlinear optical effects in integrated chalcogenide glass ring micro-resonators, resulting in improved conversion efficiency.<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"215\" src=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-57-1024x215.png\" alt=\"\" class=\"wp-image-9199\" srcset=\"https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-57-1024x215.png 1024w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-57-300x63.png 300w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-57-768x161.png 768w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-57-1536x323.png 1536w, https:\/\/www.institut-foton.eu\/wp-content\/uploads\/2024\/02\/image-57.png 1975w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\"><br>Guided mid-infrared luminescence spectra measured from rare-earth-doped chalcogenide glasses.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Related Expertise and Facilities<\/h2>\n\n\n\n<ul class=\"wp-block-list puce1\">\n<li>Design of photonic components for nonlinear optical effects and Brillouin scattering<\/li>\n\n\n\n<li>Characterization platforms for nonlinear optical effects and Brillouin scattering<\/li>\n\n\n\n<li>Nano and microfabrication through the <a href=\"http:\/\/CCLO\" data-type=\"link\" data-id=\"http:\/\/CCLO\">CCLO<\/a> Platform<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Collaborations<\/h2>\n\n\n\n<ul class=\"wp-block-list puce1\">\n<li>C2N<\/li>\n\n\n\n<li>INL<\/li>\n\n\n\n<li>CEA<\/li>\n\n\n\n<li>ICB<\/li>\n\n\n\n<li>ISCR<\/li>\n\n\n\n<li>University of Pardubice, Czech Republic<\/li>\n\n\n\n<li>CIMAP<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Related Funded Projects<\/h2>\n\n\n\n<ul class=\"wp-block-list puce1\">\n<li>ANR KASHMIR<\/li>\n\n\n\n<li>PEPR ComPhoChal&nbsp;<\/li>\n\n\n\n<li>PHC avec U.
