Greek research team has created the world’s fastest RAM

Members of the Wireless and Photonic Systems and Networks (WinPhoS) research group of the Aristotle University of Thessaloniki, created the fastest all-optical RAM cell in the world, which stores light instead of electricity.

The research team consists of Dr. Christos Vagionas, Dr. Theoni Alexoudi, PhD candidate Apostolis Tsakiridis, Nikos Pleros, Assistant Professor of the Department of Informatics of the Aristotle University of Thessaloniki and Amalia Miliou, Associate Professor of the Department of Informatics of the Aristotle University of Thessaloniki. The study was published in one of the largest scientific journals in optical technologies, Optical Letters, published by the Optical Society of America.

They demonstrate the first all-optical RAM cell that performs both Write and Read functionalities at 10 Gb/s, reporting on a 100% speed increase compared to state-of-the-art optical RAM demonstrations. To achieve this, the proposed RAM cell deploys a monolithically integrated InP optical Flip-Flop and a Semiconductor optical amplifier-Mach–Zehnder Interferometer, On/Off switch configured to operate as a strongly saturated differentially-biased access gate. Error-free operation is demonstrated at 10 Gb/s for both Write and Read operations with 6.2 dB and 0.4 dB power, respectively, achieving the fastest reported RAM cell functionalities.

The scientific achievement, which is a product of a long-term effort of the research team that started in 2009, solves a long-standing problem of computers, also known as the “Memory Wall”. According to this, the ...   Read the full article:  www.ellines.com
