Researchers Create Photonic Digital-to-Analog Converter

Researchers at George Washington University and the University of California, Los Angeles, have developed and demonstrated a photonic digital-to-analog converter without an optic-electric-optic domain crossing.
Using a silicon photonic chip platform, Volker J. Sorger, an associate professor of electrical and computer engineering at George Washington, and his colleagues have created a digital-to-analog converter that does not require the signal to be converted in the electrical domain, thus showing the potential to satisfy the demand for high data-processing capabilities while acting on optical data, interfacing to digital systems, and performing in a compact footprint, with both short signal delay and low power consumption.
The researchers describe their work in "Electronic Bottleneck Suppression in Next-Generation Networks with Integrated Photonic Digital-to-Analog Converters," published in the journal Advanced Photonics Research.
"This device is a key stepping stone for next-generation data processing hardware," Sorger says.
