We reveal a big enchancment in insertion loss for such faces, which are comparable with these of polished fibers. In this paper, we report on a new method to cleave polymer optical fibre. The most common method to cut a polymer optical fibre is chopping it with a razor blade; however, in this method both the fibre and the blade must be preheated in order to turn the material ductile, and thus, stop crazing. In this paper, we make use of the temperature-time equivalence in polymers to exchange using heating by a rise of the cleaving time and use a sawing movement to cut back fibre end face damage.

In this letter, we current a brand new methodology for making ready perpendicular finish faces in polymer optical fibers on a base of polymethyl metacrylate. Initially, a scratch is circumferentially made across the fiber. Then, the fiber is briefly cooled with liquid nitrogen or liquid nitrogen vapor, and subsequently bent over a curved surface to acquire a perpendicular fracture.

The plastic fiber taper fabricated using this technique is experimentally shown to have measurability of the refractive index of liquids. The authors fabricated a demountable Ferrule connector/Physical contact connection between silica fiber and a polymer optical fiber containing a fiber Bragg grating. The use of a connector for POF grating sensors eliminates the constraints of ultraviolet glued connections and will increase the benefit with which the devices can be applied to actual-world measurement duties.

We reveal chirped Bragg gratings fabrication in doped microstructured tapered polymer fibers by using a uniform part masks. The use of excessive photosensitive benzyl dimethyl ketal doped core fiber permits to obtain chirped Bragg gratings by means of a single krypton fluoride laser pulse. The stability of the gratings has been confirmed and the strain and temperature sensitivity measurements show their tunable properties. Finally, different tapered profiles have been applied so as to show the potentiality of this fabrication approach in polymer optical fibers. IA, first body portion 110 can also embody an indentation 112 that provides a floor for a consumer to place his or her thumb to securely hold the device 100 throughout cleaving.

In this manner, the polymer fibre may be cleaved at room temperature in seconds with the ensuing end face being of comparable high quality to those produced by extra complex and costly heated systems. We obtained chirped gratings by performing sizzling water gradient thermal annealing of uniform poly microstructured polymer optical fiber Bragg gratings . The proposed technique’s simplicity is considered one of its major advantages because no special phase masks or further etching are needed. It not solely enables straightforward management tuning of the central wavelength and chirp characteristics, but it also results in acquire versatile grating response, compared with tapered chirped POFBGs. Therefore, a versatile and low-value chirped POFBG units fabrication approach has been introduced through the use of a single uniform phase masks.
