    Researchers developed a new optical method for ultrafast analog-to-digital (A/D) conversion using Sagnac interferometers. This technique enables high-speed photonic A/D conversion without relying on complex, high-speed electronics.

    Area of Science:

    • Photonics and Optical Engineering
    • Signal Processing
    • Nonlinear Optics

    Background:

    • High-speed analog-to-digital (A/D) conversion is crucial for many applications, but is limited by electronic component speed.
    • Photonic approaches offer a potential solution to overcome these electronic limitations.

    Purpose of the Study:

    • To propose and demonstrate a novel optical quantizing and coding scheme for ultrafast A/D conversion.
    • To utilize nonlinear optical switches based on Sagnac interferometers for this purpose.

    Main Methods:

    • Employing nonlinear optical switches based on Sagnac interferometers for optical quantizing and coding.
    • Experimentally demonstrating a 3-bit A/D conversion at 10-Giga-sample-per-second (Gsps).
    • Achieving a multi-period transfer function of the Sagnac interferometer type nonlinear fiber-optic switch.

    Main Results:

    • Successful experimental demonstration of a 3-bit A/D conversion at 10 Gsps.
    • First-time experimental realization of the multi-period transfer function for Sagnac interferometer-based switches.
    • Validation of the proposed optical quantizing and coding method.

    Conclusions:

    • The proposed optical quantizing and coding method enables ultrafast photonic A/D conversion.
    • This approach bypasses the need for high-speed electronics.
    • Potential for A/D conversion rates exceeding a few hundred Gsps when combined with optical sampling.
