    Area of Science:

    • Photonics and Optical Engineering
    • Materials Science
    • Waveguide Technology

    Background:

    • Spot-size converters (SSCs) are crucial for efficiently coupling optical fibers to waveguides.
    • Polymer optical waveguides offer advantages in fabrication flexibility and cost-effectiveness.
    • Graded-index (GI) cores enable adiabatic mode transformation, essential for mode-field diameter (MFD) conversion.

    • To develop a compact, low-loss spot-size converter (SSC) using a tapered polymer optical waveguide.
    • To investigate the unique monomer diffusion characteristics in GI core formation using the Mosquito method.
    • To experimentally validate the performance of the fabricated tapered waveguide SSC.

    Main Methods:

    • Theoretical analysis of mutual monomer diffusion between core and cladding in GI polymer waveguides.
    • Development and application of the Mosquito method for fabricating tapered GI polymer waveguides.
    • Experimental fabrication and characterization of the tapered waveguide SSC at 1550-nm wavelength.

    Main Results:

    • Theoretical prediction of adiabatic MFD conversion between 4.0 and 8.6 μm in a 4 mm tapered waveguide.
    • Experimental confirmation of an 8 mm tapered waveguide SSC with 1.83 dB insertion loss.
    • Demonstrated MFD conversion from 4.7 μm to 7.5 μm at 1550-nm wavelength.

    Conclusions:

    • The developed Mosquito method enables efficient fabrication of tapered GI polymer waveguides for SSC applications.
    • The compact, low-loss SSC demonstrates effective mode-field diameter conversion.
    • This technology holds promise for improved optical coupling in various photonic systems.
