A magnitude relationship between an effective refractive index of an odd mode of a TE0 polarized wave guided through the side-by-side arrangement section and an effective refractive index of an even mode of a TM0 polarized wave guided through the side-by-side arrangement section is reversed between the starting point and an ending point of the side-by-side arrangement section. A refractive index distribution is vertically asymmetrical in an interaction section. An emission edge surface and an emission edge surface cover an entrance edge surface without excess or deficiency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Substrate-type optical waveguide element","description":"An effective refractive index of a TM0 polarized wave guided through the first core when existing alone and an effective refractive index of a TE0 polarized wave guided through the second core when ex","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9784918","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.
