“…The large insertion loss of the sample is mainly due to the mismatch of the mode fields and numerical apertures between the HCCW and SMFs. Actually, similar results can be found in many previously reported works [20][21][22][23]. A peak located at 1548.60 nm can be clearly seen in curve C of Figure 3, which corresponds to the self-imaging wavelength of the device.…”

A high sensitivity fiber-optic sensor based on self-imaging effect in a hollow-core capillary waveguide (HCCW) is presented for sensing applications. The sensor is composed of a section of HCCW fusion spliced between single mode fibers (SMFs). The self-imaging effect in the HCCW is investigated with different fiber lengths and arc-fusion parameters. By infiltrating the hollow core with index matching liquids, the peak wavelength of the proposed device shifts towards longer wavelengths. The temperature and refractive index (RI) responses of the sensor are studied systematically. When temperature is increased from 25 • C to 75 • C, the temperature sensitivity of the device can be improved significantly with the infiltrated structure, and reaches −0.49 nm/ • C, compared with that of the un-filled device, which is 9.8 pm/ • C. For the RI response, the liquid-filled structure achieves sensitivity of 12,005 nm/RIU in the range between 1.448 and 1.450, slightly higher than the 11,920 nm/RIU achieved by the un-filled one. The proposed sensor exhibits the advantages of simple structure, high sensitivity and low cost, which may find potential applications in physical and chemical sensing.

In recent years, tapered optical fibers (TOFs) have attracted increasing interest and developed into a range of devices used in many practical applications ranging from optical communication, sensing to optical manipulation and high-Q resonators. Compared with conventional optical fibers, TOFs possess a range of unique features, such as large evanescent field, strong optical confinement, mechanical flexibility and compactness. In this review, we critically summarize the multimode interference in TOFs and some of its applications with a focus on our research project undertaken at the Optoelectronics Research Centre of the University of Southampton in the United Kingdom.

- In this research, a temperature measurement technique was developed using fiber optic structured SMS and OTDR. Where in optical fibers singlemode-multimode-singlemode (SMS) and Optical Time Domain Reflectometer (OTDR) has been widely used for various sensors in detecting damage to the building earlier. Thereafter, calculations are performed using Borland Delphi's Lagrange Interpolation method 7. Characteristics of each of the fiber-optic fiber sensor structures that have been fabricated using multimode optical fibers with lengths of 5.5 cm, 6 cm, 6.5 cm and 7 cm and with use its operating wavelength is 1310 nm. Testing rangesuhusebesar 37oC - 67oC with every temperature rise of 10oC.Berdasarkan research results, multimode length 5.5 cm there is a graph increase with R2 of 93.7%. The increase in temperature, the loss of power generated greater. While the multimode length 6 cm, 6.5 cm, and 7 cm indicate that there is a decrease graph, for multimode length 6 cm with R2 equal to 97,7%, for multimode length 6,5 cm with R2 equal to 99,7%, for long multimode 7 cm with R2 99.2%. While based on result of calculation by Lagrange Interpolation method for suhuberstruktur SMS sensor based on result of calculation using Lagrange Interpolation method with different multimode length have same data regularity compared to temperature sensor structured SMS based on measurement result. For example, as long as 7 cm long multimode yield R2 of 99.2% for the measurement result and yield R2 of 99.3% for the calculation result.
