The ferroelectric layer includes a ridge comprising a channel optical waveguide, first and second protuberances on opposite sides of the ridge, inner grooves between the ridge and protuberances, respectively, and outer grooves outside of the protuberances, respectively. The outer groove is deeper than the inner groove. The ridge portion has a width of 6.6 μm-8.5 μm, a distance of an outer edge of the first protuberance and an outer edge of the second protuberance is 8.6 μm-20 μm, the inner groove has a depth of 2.0 μm-2.9 μm, and the outer groove has a depth of 2.5 μm-3.5 μm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical waveguide devices and harmonic wave generating devices","description":"An optical waveguide device includes a ferroelectric layer having a thickness of 4 μm-7 μm; a supporting body; and an adhesive layer adhering a bottom face of the ferroelectric layer and supporting bo","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8542434","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.
