A method for fabricating a waveguide structure to form a solid-core waveguide may include forming a first trench, a second trench, and a third trench in a substrate layer, and depositing a waveguiding layer on the machined substrate layer, wherein depositing the waveguiding layer creates a hollow core of a fluid channel in a location corresponding to the first trench, and a solid-core waveguide portion in the waveguiding layer in a location corresponding to an area between the second trench and the third trench."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fabrication of waveguide structures","description":"A method of fabricating a waveguide structure to form a solid-core waveguide from a waveguiding layer may include etching a fluid channel into the waveguiding layer, etching a first air-gap and a seco","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11480733","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.
