Further, the second core layer and the quantum well layer are close to each other within a range of a mode field of light guided in the second core layer, and the first core layer is butt-jointed to the second core layer and the quantum well layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical integrated element and optical module","description":"An optical integrated element includes: a substrate; a first waveguide region in which a lower cladding layer, a first core layer, and an upper cladding layer are sequentially laminated in this order ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11281029","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.
