An optical modulator individually modulates the M number of light beams that were emitted. When a first light-emitting element driven normally fails, the first light-emitting element is stopped and a second light-emitting element that was stopped is driven, thereby maintaining the emission of the modulated M number of light beams."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical transmitter and optical communication device","description":"At least two light-emitting elements emit light to a branching device, and the branching device divides the light that entered into an input port into at least two and emits the light from M number of","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9628190","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.
