The apparatus comprises an electro-absorption modulator and a back current detector. The electro-absorption modulator receives an electronic digital signal from an electro-absorption driver. The electro-absorption modulator modulates the beam of the laser according to the electronic digital signal. While modulating the beam, the electro-absorption modulator produces a back current. This back current is proportional to the optical power of the beam. The back current detector measures the back current to determine the optical power of the beam."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for modulating a laser beam and sensing the optical power thereof","description":"A method and apparatus for modulating a beam from a laser with an electro-absorption modulator, and determining the optical power of the beam by measuring a back current produced by the electro-absorp","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9671283","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.
