    A novel fiber optic coupler for lithium niobate waveguides was developed. This device allows for efficient light coupling and can recover from fiber displacement, minimizing signal loss in optical systems.

    Area of Science:

    • Optoelectronics
    • Materials Science

    Background:

    • Integrated optics relies on efficient coupling between optical fibers and waveguides.
    • Lithium niobate (LiNbO3) is a key material for electro-optic devices, often utilizing strip waveguides.
    • Achieving high and stable coupling efficiency is crucial for device performance.

    Purpose of the Study:

    • To develop and characterize a single-mode fiber coupler for titanium-diffused lithium niobate strip waveguides.
    • To investigate the impact of axial and angular misalignments on coupling efficiency.
    • To design a coupler with a self-recovery feature for coupling degradation.

    Main Methods:

    • Fabrication of a single-mode fiber coupler for LiNbO3 strip waveguides.
    • Experimental investigation of coupling efficiency at a 6328 Å wavelength.

  • Analysis of coupling performance under various axial and angular fiber displacements.
  • Evaluation of the coupler's recovery capability after displacement-induced degradation.

    • Main Results:

    • The developed coupler demonstrates efficient light coupling to a 4 µm wide, 8 mm long LiNbO3 strip waveguide.
    • Coupling efficiency is sensitive to three axial and two angular misalignments.
    • A unique feature allows the coupler to recover initial coupling efficiency after fiber displacement.
    • The total optical insertion loss after fixing the fiber is 3 dB.

    Conclusions:

    • A robust single-mode fiber coupler for LiNbO3 strip waveguides has been successfully devised.
    • The coupler's design addresses practical challenges of fiber alignment and stability.
    • The self-recovery mechanism enhances the reliability and longevity of optical interconnections.
