    A new on-chip linearization method suppresses third-order intermodulation distortion (IMD3) in microwave photonic links using integrated ring resonators. This technique achieves significant IMD3 reduction and enhances spurious-free dynamic range (SFDR) for integrated photonic circuits.

    Area of Science:

    • Photonics
    • Microwave Engineering
    • Integrated Optics

    Background:

    • Microwave photonic links are crucial for high-frequency signal transmission.
    • Linearity is a key challenge in phase-modulated microwave photonic links, often limited by third-order intermodulation distortion (IMD3).

    Purpose of the Study:

    • To propose and experimentally validate an on-chip linearization method for phase-modulated microwave photonic links.
    • To suppress IMD3 components by controlling optical sidebands using integrated ring resonators.

    Main Methods:

    • Theoretical analysis of IMD3 suppression mechanisms.
    • Implementation of an on-chip linearization technique using integrated ring resonators.
    • Experimental verification of the proposed method.
