This modulation format enables the optical receiver to perform direct optical detection using a Stokes-vector detector to fully recover the encoded data. In an example embodiment, the corresponding signal processing at the optical receiver may include: determining a Stokes-space rotation matrix corresponding to the polarization-state rotation encountered by the PDM signal in the optical transport link; applying the determined Stokes-space rotation matrix to the Stokes sub-vector measured by the Stokes-vector detector to estimate the Stokes sub-vector of the PDM signal at the originating optical transmitter; converting the estimated Stokes sub-vector into the corresponding Jones vector; and recovering the data by decoding the polarization components of the Jones vector."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Stokes-vector-based transmission and detection of optical polarization-division-multiplexed signals","description":"We disclose an optical transport system configured to transport data using a PDM-modulation format, in which each of two orthogonal polarizations is independently amplitude-modulated, and the relative","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9641279","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.
