    We developed a photonic processor for optical temporal convolution, converting results into a 300 GHz wireless signal. This optical approach significantly reduces computational cost and latency compared to electronic methods.

    Area of Science:

    • Photonics
    • Optical Computing
    • Wireless Communication

    Background:

    • Temporal convolution is crucial for signal processing.
    • Electronic implementations face limitations in speed and power consumption.
    • Photonic approaches offer potential for high-speed, low-latency computation.

    Purpose of the Study:

    • To demonstrate a novel comb-based photonic processor for temporal convolution.
    • To convert the analog optical computation result directly into a high-frequency wireless signal.
    • To evaluate the computational cost and latency benefits over electronic systems.

    Main Methods:

    • Utilizing a dissipative Kerr soliton microcomb with a 300 GHz free spectral range for parallel channels.
    • Encoding convolution kernels as comb-line weights and processing via dispersion-induced delays.
