The structure has an extremely low reflectivity and an extremely high transmission rate, thus facilitating an integration of a large-scale light path."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Right-angle waveguide based on circular-cylinder-type square-lattice photonic crystal and single compensation scattering cylinder with high refractive index","description":"A high-refractive-index single-compensation-scattering-cylinder right-angle waveguide of a cylindrical square lattice photonic crystal, being a photonic crystal formed by arranging a first dielectric ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9784916","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
