Area of Science:

  • Optoelectronics
  • Materials Science

Background:

  • All-optical signal processing seeks alternatives to current data transmission.
  • Fiber optic amplifiers, like Erbium-doped ones, are crucial but expensive to produce.
  • High-temperature, high-purity fabrication limits scalability and cost-effectiveness.

Purpose of the Study:

  • To develop cost-effective, room-temperature fabricated polymer fiber amplifiers.
  • To evaluate their performance for optical signal amplification.
  • To explore potential for multiwavelength operations.

Main Methods:

  • Fabrication of near-infrared polymer fibers using a room-temperature process.
  • Characterization of amplified spontaneous emission (ASE) and optical losses.
  • Assessment of gain coefficients and suitability for optical amplification.

Main Results:

  • Achieved near-infrared polymer fiber amplifiers with a working band of ~20 nm.
  • Demonstrated good gain coefficients and low optical losses (a few cm⁻¹).
  • Identified high fiber quality and low self-absorption as key factors for amplification.

Conclusions:

  • The developed polymer fiber amplifiers are cost-effective and fabricated at room temperature.
  • Their performance is suitable for short-distance optical signal processing.
  • Potential for multiwavelength operation exists using various doping dyes.
