The structure of the present invention, which is compact in structure and ease of integration with other optical logic elements, not only can realize the functions of the high-contrast photonic and logic gate, but also has high contrast of high and low logic output; and is widely applicable to optical communication bands."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High-contrast photonic crystal “and” logic gate","description":"The present invention discloses a high-contrast photonic crystal AND logic gate, comprising a five-port two-dimensional photonic crystal, a nonlinear cavity unit and a Y-shape AND logic gate unit; and","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10473854","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.
