Advancing Data Transmission with High-Dimensional Encoding

"By utilizing intermodal dispersion in multimode fibers (MMFs), we achieved high-dimensional semantic encoding and decoding in the frequency domain. Mapping symbols to distinct frequencies enabled a seven-fold increase in transmission capacity compared to traditional encoding methods. Additionally, integrating PAM-4 enhanced spectral efficiency, reaching 9.12 bits/s/Hz with zero decoding errors."

Enhancing Noise Tolerance for Sentiment Analysis

"In addition to increasing transmission capacity, we applied our system to sentiment analysis using the IMDb movie review dataset. By encoding semantically similar symbols to adjacent frequencies, we significantly improved noise tolerance, enabling accurate sentiment analysis even under high symbol error rate conditions. This demonstrates the potential of MMF-based semantic communication to enhance both capacity and resilience in optical communication systems, making it highly suitable for bandwidth-limited and noisy environments."

The Future of Optical Semantic Communication

"Utilizing MMFs for semantic communication marks a major leap in optical communications. The ability to directly transmit semantic information through optical frequencies—combined with high capacity and resilience—positions this technology as a promising solution for the future of communication systems."

The Growing Demand for Smarter Communication

With increasing global reliance on fast and efficient communication, traditional data transmission systems are reaching their limits. Semantic communication offers a groundbreaking solution by prioritizing meaning over raw data, reducing bandwidth consumption while improving efficiency.
