Researchers from George Washington University (GWU) and UCLA developed and demonstrated a photonic digital-to-analog converter without leaving the optical domain. The technology has the potential to advance next-generation data-processing hardware, with implications for data centers, 6G networks, and AI, among others.
GWU associate professor Volker J. Sorger and his colleagues used a silicon photonic chip platform to create a digital-to-analog converter (DAC) that does not require the signal to be converted into the electrical domain.
“We realized that there is a fundamental disconnect between electrical signals being digital, and optical information processing, which is analog,” Sorger told Photonics Media….READ MORE
