Among them, optical biosensors\u2014particularly those based on resonators such as ring resonators\u2014stand out for their high sensitivity and ability to detect small changes in the refractive index. In this work, we designed the structure of the resonator ring, this structure was selected as the most suitable due to its advantageous operational principles, illustrated in Figure 1.<\/p>\n<h2>Methodology<\/h2>\n<p>Ring resonator-based optical biosensors were designed and simulated using the software COMSOL to optimize sensitivity, quality factor, and detection limits. Using Silicon and Silicon Dioxide as materials of Cladding and Core, respectively. Key geometric parameters are Radius of curvature (R) : 62 \u03bcm<br \/>\nCladding width (Wr): 2 \u03bcm<br \/>\nCore width (Wi): 0.2 \u03bcm<br \/>\nGap (dx): 0.7 \u03bcm, with the modeled structure shown in Figure 2.<\/p>\n<h2>Results<\/h2>\n<p>The electric field distribution reveals the resonant modes.<br \/>\nThe figure 4 show the optimization of the transmission spectrum of a ring resonator. Obtained values of FWHM: 0.3 nm represents the full width at half maximum of the resonance dip. A FSR of 2.7 nm indicated the free spectral range between consecutive resonances. A High Q-factor of 1.5 \u00d7 106<\/p>\n<h2>Conclusions<\/h2>\n<p>The optimized ring resonator biosensor, built with silicon and silicon dioxide, achieved high Q- factors (~10\u2076), demonstrating strong sensitivity and compact design. Its performance is comparable to advanced structures like microdisks and photonic crystals. This makes it a promising candidate for lab-on- chip and clinical sensing applications.<\/p>","protected":false},"featured_media":1606,"template":"template-poster-p2025.php","categories":[12],"colaboracion":[253,254],"investigador":[252,251,250],"tipo":[6],"class_list":["post-1601","poster","type-poster","status-publish","has-post-thumbnail","hentry","category-12","colaboracion-universidad-autonoma-de-coahuila","colaboracion-universidad-autonoma-de-san-luis-potosi","investigador-de-rodriguez-obregon","investigador-eleazar-samuel-kolosovas-machuca","investigador-juan-manuel-nunez-leyva","tipo-electronicos"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Parametric Optimization of Optical Ring Resonators for Biomedical Biosensing Applications<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.unitec.edu\/conicieti\/es\/poster\/parametric-optimization-of-optical-ring-resonators-for-biomedical-biosensing-applications\/\" \/>\n<meta property=\"og:locale\" content=\"es_MX\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Parametric Optimization of Optical Ring Resonators for Biomedical Biosensing Applications\" \/>\n<meta property=\"og:description\" content=\"Abstract Biosensors, which emerged in the 1960s, convert biological interactions into measurable signals through a system comprising recognition, transduction, and signal processing elements.
