    Area of Science:

    • Optical Engineering
    • Telecommunications

    Background:

    • Fiber optic splices are critical for signal transmission but can introduce undesirable mode conversion.
    • Splicing conditions significantly affect the transmission characteristics of optical fibers.

    Purpose of the Study:

    • To quantify mode conversion losses at fiber optic splices.
    • To develop and evaluate a mode scrambler for mitigating splice-induced signal degradation.

    Main Methods:

    • Measurement of mode conversion at various fiber optic splices.
    • Fabrication and testing of a novel mode scrambler.
    • Analysis of output waveforms for individual modes and total signal.

    Main Results:

    • The best splice, with <0.01 dB loss, still resulted in ~11% power loss due to mode conversion.

    Transmission of Multiple Signals through an Optical Fiber Using Wavefront Shaping

    Published on: March 20, 2017

  • A fabricated mode scrambler exhibited low insertion loss (<0.3 dB for a laser diode).
  • The mode scrambler ensured identical output waveforms for each mode and the total signal.

    • Conclusions:

    • Fiber optic splices inherently cause significant mode conversion, affecting signal quality.
    • A simple, effective mode scrambler can successfully mitigate deviations in transmission characteristics caused by splices.
    • The developed mode scrambler maintains signal integrity by ensuring consistent mode behavior.
