Fiber Optic Center Technical Paper:

Doped Fiber Technology

This technical paper describes the sequence of procedures involving both technology and technique of preform fabrication, fiber draw, measurements, and basic understanding of waveguide propagation and laser fundamentals.



  • Rare Earth Doped Fibers - “The evolution of the main processes for making doped fiber preforms.”
  • Thulium-Doped Fibers – “Using thulium to handle rare-earth dopants during MCVD preform fabrication.”
  • Fabricating Doped Fiber Preforms - “Making doped fiber preforms with halide-process MCVD core rods.”
