Thus, it is possible to stably perform phase modulation with high precision."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Driving method and driving apparatus for optical modulator, and optical transmitter using same","description":"A driving apparatus supplies a drive signal to an optical modulator corresponding to a phase modulation format, and also, divides a part of an output light from the optical modulator; extracts some op","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8483576","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.
