    Area of Science:

    • Photonics and Optical Engineering
    • Integrated Optics
    • Waveguide Technology

    Background:

    • Current silicon photonics optical phased arrays face limitations in achieving both small beam divergence and large field-of-view due to high index contrast.
    • Existing solutions often require increased fabrication complexity to overcome these limitations.

    Purpose of the Study:

    • To propose a novel waveguide grating antenna design for silicon photonics.
    • To overcome the simultaneous requirement of small beam divergence and large field-of-view in optical phased arrays.
    • To maintain compatibility with existing silicon photonics fabrication processes.

    Main Methods:

    • Proposed an ultra-long waveguide grating antenna design.
    • Incorporated subwavelength segments within the evanescent field of a conventional strip waveguide.
    • Utilized the bound state in the continuum effect to suppress sidewall emission.

    Main Results:

    • Theoretically demonstrated a millimeter-long through-etched waveguide grating antenna.
    • Achieved a minimal beam divergence angle of 0.081°.
    • Maintained feature sizes compatible with current silicon photonics foundries.

    Conclusions:

    • The proposed ultra-long waveguide grating antenna effectively resolves the trade-off between beam divergence and field-of-view in silicon photonics.
    • The design leverages bound state in the continuum for enhanced performance.
    • This approach offers a fabrication-compatible solution for advanced optical phased arrays.
