Integrated sensors and transmitters of a wide variety of human physiological indicators have recently emerged in the form of multimaterial optical fibers. The methods utilized in the manufacture of optical fibers facilitate the use of a wide range of functional elements in microscale optical fibers with an extensive variety of structures. This article presents an overview and review of semiconductor multimaterial optical fibers, their fabrication and postprocessing techniques, different geometries, and integration in devices that can be further utilized in biomedical applications. Semiconductor optical fiber sensors and fiber lasers for body temperature regulation, in vivo detection, volatile organic compound detection, and medical surgery will be discussed.

“…In the past, mid-infrared laser sources proved to have high efficiency in hard tissue ablation while reducing mechanical stress on the cutting edges. [3][4][5][6] Several in-vivo studies with animals showed that laser osteotomy leads to faster bone healing and less thermal damage compared to saws and drills. [7][8][9] Hard tissue ablation with infrared laser sources is based on thermo-mechanical ablation.…”

Thermo-mechanical hard tissue ablation with pulsed mid-infrared lasers is an efficient and minimally invasive method for precise bone cutting. The efficiency of the ablation process strongly depends on the absorption of laser radiation in the intracellular water of hard tissue. Therefore, 3 µm laser sources show high efficiency in bone ablation with a small heat affected zone. Until now, it was not possible to transfer this high efficiency into high ablation rates because of the limited repetition rate of commercially available laser sources. In this study, we demonstrate ablation experiments on bovine bone tissue utilizing a novel 3 µm laser source with a repetition rate of 12 kHz and nanosecond pulse duration. We optimized process parameters especially focus position, flow rate of a water spray system and pulse overlap for a fast and non-thermal ablation process. By optimizing the optical system, we were able to realize a fluence for fast bone ablation with rates of up to 2.2 mm 3 /s and a maximum ablation depth of 3.4 mm. For further increase of the depth-dependent ablation rate, it was possible to estimate required beam caustic and laser specifications.
