“…When one reviews the current literature, one can see that there is an incomparable increase in optics. Some important topics we have chosen from the literature studies that we think will be useful in this sense are as follows; models for pulse propagation on fibers [1], analysis of edge filtering for fiber Bragg gratings sensors [2], classification of plastics using lasers [3], phase difference of electromagnetic waves [4] and optical solitons of Schrödinger equation in case of potential and nonlinearity [5].…”

In this study, we have focused on finding soliton solutions of the cubic-quartic Fokas-Lenells equation, which models the nonlinear pulse transmission through optical fiber, is a pretty new and updated model. We have used three different efficient analytical methods, namely, the Sinh-Gordon expansion method, enhanced modified extended tanh expansion method and unified Riccati equation expansion method. By modifying our proposed method and using it effectively, we have obtained much more optical solutions. We have supported the results with the 3D surface, 2D and contour plots of the soliton solutions, such as singular, periodic, periodic-singular, dark and M-shaped solitons. The originality of the method we propose is that it has never been used before. With the innovation of the method, we have obtained M-shaped solitons, which are very rarely obtainable in soliton waves. On the other hand, enhanced modified extended tanh expansion method have provided us more extra solutions. As the last and most important part, in order to examine physical behaviors, we have investigated the effect of the coefficient of the fourth order dispersion parameter on wave propagation by presenting the graphical representation.

“…There is interference between the two modes and the MMF in the SMS fiber structure and produces the maximum or minimum interference. Optimizing the MMF into the sensor can develop the function [18,19] and sensor sensitivity with the displacement principle. The difference influences this in refractive index and NA between SMF and MMF on the SMS fiber structure…”

The research has measured the landslide using a displacement sensor based on Glass Optical Fiber (GOF) and Optical Time Domain Reflectometer (OTDR). The sensor manufacture process consists of various materials, structures, configurations, diameters, and directions. The sensor is made using GOF with a single-mode structure and single mode-multimode-Singlemode (SMS) structure. Each system is given a variety of configurations, namely gamma, bowknot, and three loops configuration. Each arrangement is provided a variation of the indentation diameter in three displacement directions. The test results will be read as the power loss on the OTDR in dB units. The results obtained were then compared between two materials, two structures, and directions. Displacement resulting landslides and changes to the sensor, causing power losses, and affecting the characteristics of each sensor. We found the best measurement results with the sensitivity value of 0.241 dB/mm and the resolution value of 0.004 mm. The displacement sensor has been made for measuring landslide in the laboratory-scale simulation based on GOF and OTDR with easier fabrication, easy operation, high sensitivity, better resolution and can be connected to a computer

“…The underlying principle of such spliced ber is the multi-mode interference (MMI). As the MMF length is the main factor contributing to the different slopes' regions of the spectrum, hence the MMF length has been optimized as described in our previous work [17]. One of the slope edges of the spectrum has been chosen as per the requirement and employed in the proposed technique.…”

In this article, we have extensively investigated the e ciency of etched silica-based ber Bragg gratings (FBGs) for the experimental measurement of temperature and strain simultaneously. A single-multi-single mode ber (SMS) combination is employed in the circuitry which acts as a bandpass lter for e cient interrogation technique. We recorded the sensitivity of 20.30 pm/°C and 2.89 pm/µ over the temperature and strain range of 25-225°C and 50-2050 µ , respectively. These data were recorded with the strain resolution of ± 10 µ whereas the resolution for the temperature is ± 0.50°C. The experimental results show the potentiality of the sensor for measuring the strain and temperature simultaneously with higher intrinsic sensitivity and resolution.
