Innovations in High-Speed Smart Pixel Arrays for Advanced Optical Communication

DESCRIPTION

This presentation by Mr. Ranjith C. Shahid and Ms. Kavya K. M explores high-speed smart pixel arrays (SPAs) utilized in optoelectronic integrated circuits (OEICs) for advanced telecommunications. Key discussion points include a literature survey, introduction to smart pixel array components, including modulators, processing element (PE) arrays, and photo receivers. The application of SPAs in data communication networks is highlighted, emphasizing their potential for improved data retrieval rates and reduced interference. Future directions are proposed for enhancing SPA technology.
