    Researchers developed a new method for designing broadband waveguide couplers. This technique effectively cancels chromatic orders, enabling wider spectral bandwidths for optical devices.

    Area of Science:

    • Optics and Photonics
    • Materials Science

    Background:

    • Waveguide couplers are essential components in integrated optics.
    • Achieving broadband operation in waveguide couplers is challenging due to chromatic dispersion.

    Purpose of the Study:

    • To present a general design approach for broadband waveguide couplers.
    • To compensate for chromatic dispersion in waveguide devices.

    Main Methods:

    • Utilizing a double-parallel grating assembly to cancel the first chromatic order.
    • Selecting specific prism glass and base angles to compensate for the second chromatic order.

    Main Results:

    • The developed technique was successfully applied to a Corning glass 7059 waveguide.
    • A spectral bandwidth of 70 nm was experimentally measured.
