Profs. Volker J. Sorger and Tarek El-Ghazawi (ECE) as the PI and co-PI, are funded jointly by the National Science Foundation and the Semiconductor Research Corporation (SRC) with a 3-year $1,330,000 grant.Profs. Volker J. Sorger and Tarek El-Ghazawi (ECE) are the principal investigator and co-principal investigator, respectively, on a three-year, $1,330,000 grant funded jointly by the National Science Foundation and the Semiconductor Research Corporation (SRC) under the highly competitive and prestigious Energy-Efficient Computing: from Devices to Architectures (E2CDA) program. The project is titled “Collaborative Research: Nanophotonic Neuromorphic Computing.” Profs. Sorger and El-Ghazawi are collaborating on the grant with Prof. Pruncal (Princeton University). The E2CDA program addresses the problem that future performance improvements across the board are now severely limited by the amount of energy it takes to manipulate, store, and transport data. Under this innovative and interdisciplinary project, the PIs will develop future nano-photonic neuromorphic processors, inspired by the brain. This project is a part of a longer range vision and direction by Profs. El-Ghazawi and Sorger to achieve orders of magnitude improvements over today’s computing technologies through nano-photonic-enabled computing (NEC), using innovative principles for processing and architectures that depart from the traditional von Neumann digital computer systems and their limitations.

Prof. Tarek El-Ghazawi (ECE) and Professor Volker J. Sorger (ECE) are the principal investigator and co-principal investigator, respectively, on a four-year, $900,000 grant funded by the National Science Foundation (NSF).The project is titled “RAISE: The Reconfigurable Optical Computer (ROC)”. The ultimate goal of this bold interdisciplinary project is to engender a new class of reconfigurable computing devices. In specific, the objective is to create a nanophotonic analog reconfigurable computer (ROC) that is capable of computing out of first principles by solving those partial differential equations (PDEs) that are used for most simulations in science and engineering. The PDEs would be directly solved using a network of electric components that are implemented using innovative nanophotonic devices. Due to its transformative and interdisciplinary nature, this project is jointly funded by the Engineering and CISE Directorates in NSF.

Congratulate Shuai Sun on wining the Entrepreneurship Award of the 2017 SEAS R&D Showcase!Shuai participated the 2017 SEAS R&D Showcase and won the Entrepreneurship Award with $2,000 prize money.
His presentation with the title "Hybrid Photonic Plasmonic Interconnect (HyPPI): The New Path of Moore's Law in CLEAR Light" mainly talks about a holistic figure of merit (FOM) termed Capability-to-Latency-Energy-Amount-Resistance (CLEAR) to adequately compare the recent technology paradigms which not only includes the components count, but also considers the communication delay, energy efficiency, on-chip scaling and also the economic cost of a interconnect. Moreover, it accurately and equitably postdicts the technology developments since the 1940’s until today, and predicts photonics as a logical extension to keep-up the 2x/year pace of information-handling machines. At last, since this FOM is derived bottom-up, it is able to provide remarkable adaptability to applications ranging from device- and link-level to network- and system-level. Applying CLEAR to benchmark the performance under these levels against fundamental physical compute and communication limits shows that HyPPI is competitive even for fractions of the die-size, thus making a case for on-chip optical interconnects and network applications. |
