    Area of Science:

    • Photonics
    • Artificial Intelligence
    • Computer Science

    Background:

    • Neuromorphic photonic computing offers potential for advanced AI accelerators due to its speed and low energy consumption.
    • Current neuromorphic photonic systems face limitations in scalability due to large, discrete components.

    Purpose of the Study:

    • To propose a novel, compact, and scalable architecture for photonic spiking neural networks (PSNNs).
    • To demonstrate the feasibility of using a directly modulated laser and a distributed feedback laser with a saturable absorber (DML-DFB-SA) for PSNNs.
    • To enhance energy efficiency and integration capabilities in neuromorphic photonic computing.

    Main Methods:

    • Developed a PSNN architecture integrating a directly modulated laser (DML) as the optical source and electro-optic converter, and a distributed feedback laser with a saturable absorber (DFB-SA) as the spiking neuron.
    • Employed a time-multiplexed spike coding scheme to enable single neurons to emulate multiple functionalities.
    • Fabricated DML and DFB-SA laser chips on Indium Phosphide (InP) substrates for potential large-scale integration.

    Main Results:

    • Achieved a remarkable energy efficiency of 0.625 pJ/MAC.
    • Demonstrated robust performance against the chirp effect of the DML in short-distance transmissions.
    • Attained a 94% recognition accuracy on the MNIST dataset using the proposed DML-DFB-SA system with time-multiplexed coding.

    Conclusions:

    • The DML-DFB-SA architecture offers a compact, energy-efficient, and scalable solution for neuromorphic photonic computing.
    • This approach facilitates the development of large-scale integrated PSNN chips for next-generation AI accelerators.
    • The system's robustness and high performance make it a promising candidate for practical PSNN applications.
