    Area of Science:

    • Photonics
    • Optical Engineering
    • Materials Science

    Background:

    • Few-mode optical amplifiers are crucial for increasing data transmission capacity.
    • Existing amplifiers often struggle with modal gain balancing and intermodal crosstalk.
    • Polymer optical waveguides offer potential advantages in cost and fabrication.

    • To experimentally demonstrate a novel few-mode optical waveguide amplifier.
    • To achieve simultaneous amplification of multiple spatial modes with balanced gain.
    • To investigate the performance characteristics, including gain, crosstalk, and noise figure.

    Main Methods:

    • Design and fabrication of a square few-mode polymer optical waveguide amplifier.
    • Utilizing erbium-ytterbium codoping for optical gain.
    • Employing mode-selective photonic lanterns for multiplexing/demultiplexing.
    • Implementing a reconfigurable pump configuration to balance modal gain.

    Main Results:

    • Achieved an average gain of 10.4 dB per mode at 1555 nm in a 1.5 cm waveguide.
    • Demonstrated ultralow differential modal gain of 0.4 dB.
    • Simultaneously amplified LP01, LP11, and LP21 modes across the C-band with low noise figures.

    Conclusions:

    • This work represents the first experimental realization of a few-mode optical waveguide amplifier.
    • The developed amplifier shows promising performance for future high-capacity optical communication systems.
    • The reconfigurable pump scheme effectively balances modal gain, minimizing differential gain.
