Silicon Photonics Accelerates On-Chip Neural Network Training

Facebook X LinkedIn Email
Researchers from George Washington University (GWU) have introduced a strategy for training deep neural networks the benefits of using photonics to execute artificial intelligence (AI) applications. The team’s CMOS-compatible silicon photonics architecture enabled parallel, ultrafast on-chip training of neural networks with low energy consumption. According to professor Volker Sorger, the hardware that keys the advancement will accelerate the speed of training of machine learning systems, and harness the best of what both photonics and electronic chips offer integrated systems. ...Read full article

    integrated photonics
    Integrated photonics is a field of study and technology that involves the integration of optical components, such as lasers, modulators, detectors, and waveguides, on a single chip or substrate. The goal of integrated photonics is to miniaturize and consolidate optical elements in a manner similar to the integration of electronic components on a microchip in traditional integrated circuits. Key aspects of integrated photonics include: Miniaturization: Integrated photonics aims to...
    deep learning
    Deep learning is a subset of machine learning that involves the use of artificial neural networks to model and solve complex problems. The term "deep" in deep learning refers to the use of deep neural networks, which are neural networks with multiple layers (deep architectures). These networks, often called deep neural networks or deep neural architectures, have the ability to automatically learn hierarchical representations of data. Key concepts and components of deep learning include: ...
    integrated optics
    A thin-film device containing miniature optical components connected via optical waveguides on a transparent dielectric substrate, whose lenses, detectors, filters, couplers and so forth perform operations analogous to those of integrated electronic circuits for switching, communications and logic.
    multiplexing
    The combination of two or more signals for transmission along a single wire, path or carrier. In most optical communication systems this is referred to as wavelength division multiplexing, in which the combination of different signals for transmission are imbedded in multiple wavelengths over a single optical channel. The optical channel is a fiber optic cable or any other standard optical waveguide.
