The Mach-Zehnder modulator includes a Mach-Zehnder (MZ) optical waveguide including two arm waveguides, a 1×2 multimode interference coupler composed of a semiconductor that splits and distributes input light to the two arm waveguides, a 2×1 multimode interference coupler composed of a semiconductor that multiplexes light from the two arm waveguides, and phase modulation means for giving a phase difference to the light that propagates through the two arm waveguides, wherein the 1×2 multimode interference coupler and the 2×1 multimode interference coupler are formed in a high-mesa structure, and higher mode light radiation means for radiating higher mode light is connected to only the 2×1 multimode interference coupler among the two multimode interference couplers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor Mach-Zehnder optical modulator and IQ optical modulator using same","description":"A Mach-Zehnder modulator is enabled to perform high-speed modulation operation by reducing RF loss of a high-frequency wiring formed on an optical waveguide without deteriorating optical characteristi","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11275287","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.
