The optical waveguide includes a core and a lateral clad. The core extends in a spiral shape above a surface of the substrate. The lateral clad is disposed in a same layer as the core above the surface of the substrate and is in contact with either side surfaces of the core. At least a part of a surface of the core located opposite from the substrate is a transmission surface from which light leaks and is absorbed by a detected object."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical waveguide sensor and manufacturing method of the same","description":"An optical waveguide sensor includes a substrate and an optical waveguide.
