“…However, there are disadvantages of using these techniques, such as structural damages and environmental effects. Laser ablation for removal of material has been found to overcome the limitations of traditional methods . Further, researchers are investigating laser ablation for jacket striping of single‐mode fiber, which has a dual polymer layer system …”

Laser ablation (LA), which employs a pulsed laser to remove materials from a substrate for generating micro-/nanostructures, has tremendous applications in the fabrication of metals, ceramics, glasses and polymers. It has become a noteworthy approach for achieving various functional structures in engineering, chemistry, biology, medicine and other fields. Polymers are one such class of materials; they can be melted and vaporized at high temperature during the ablation process. A number of polymers have been researched as candidate substrates in LA, and many different structures and patterns have been realized by this method. The current states of research and progress are reviewed from basic concepts to optimal parameters, polymer types and applications. The significance of this paper is to provide a basis for follow-up research that leads to the development of superior materials and high-quality production through LA. In this review, we first introduce the basic concept of LA, including mechanism, laser types (millisecond, microsecond, nanosecond, picosecond and femtosecond) and influential parameters (wavelength, repetition rate, fluence and pulse duration). Then, we focus on several commonly used polymer materials and compare them in detail, including the effects of polymer properties, laser parameters and feature designs. Finally, we summarize the applications of various structures fabricated by LA in a variety of areas along with a perspective of the challenges in this research area. Overall, a thorough review of LA of several polymers is presented, which could pave the way for characterization of future novel materials.

“…Other authors have investigated and demonstrated the use of CO 2 lasers to ablate and remove the polymer coating [20]. We are currently in the process of implementing this technique which should eventually allow for a completely operator independent, automated fibre end-face preparation system.…”

Reproducible, precise cleaving of optical fibres is of great importance to the fibre laser and telecommunications industries. We present a novel approach to the end-face processing of optical fibres using a 9.6 µm CO 2 laser to produce flat, smooth and symmetric fibre end-face profiles with no rounding or melting at the edges of the fibre. As a demonstration, precision cleaving of a 400 µm diameter optical fibre is reported. For this fibre a topographical profile height of <400 nm (0.06°) and a reproducibility better than 200 nm (0.03°) was achieved. To the best of our knowledge this is the first demonstration of a CO 2 process that has generated a fibre endface topography substantially smaller than a typical mechanical cleave. Highlighting the flexibility of this system, we have also demonstrated the generation of near arbitrary fiber end-face profiles such as discrete phase steps and non-spherical surface profiles.

We present a technique to rapidly and automatically produce sections of optical fibre and load them into arrays such that they can be nano-imprinted in parallel. The technique makes use of automated fibre feeding, cutting and alignment with microfabricated groove arrays. The system is analyzed and optimized and it is found that the geometry of the arrays themselves is a critical factor. Three types of array are investigated-simple grooves, grooves with lateral funnels at the input, and bulk silicon machined V-groove arrays with funnels in both lateral and vertical dimensions. It is found that the incorporation of funnels significantly increases the accuracy of loading, overcoming the need for precise alignment, such that a throughput nearing 1000 fibre segments an hour can be achieved. This system forms part of a sequence of novel processes for the production of nano-photonic sensors.
