“…POF has the benefit of an easy connection and a large core, which could be an economic solution for the in-home network. Different kinds of materials are implemented for POF fabrication, such as polymethyl methacrylate (PMMA) [ 3 , 4 ], polydimethylsiloxane (PDMS) [ 5 , 6 ], polycarbonate (PC) [ 7 , 8 ], polystyrene (PS) [ 9 , 10 ], perfluorinated polymer (commercially known as CYTOP ® (AGC, Inc., Tokyo, Japan) [ 11 , 12 ], cycloolefin polymer (commercially known as ZEONEX ® *ZEON (Corporation, Tokyo, Japan)) [ 13 , 14 ], and cycloolefin copolymer (commercially known as TOPAS ® ) (TOPAS Advanced Polymers, Farmington Hills, MI, USA) [ 15 , 16 ]. The flexibility of POF material allows for the production of POFs with varying specifications or materials to meet the needs of various applications.…”

We investigate mode coupling in a multimode graded-index microstructured polymer optical fiber (GI mPOF) with a solid core by solving the time-independent power flow equation (TI PFE). Using launch beams with various radial offsets, it is possible to calculate for such an optical fiber the transients of the modal power distribution, the length Lc at which an equilibrium mode distribution (EMD) is reached, and the length zs for establishing a steady-state distribution (SSD). In contrast to the conventional GI POF, the GI mPOF explored in this study achieves the EMD at a shorter length Lc. The earlier shift to the phase of slower bandwidth decrease would result from the shorter Lc. These results are helpful for the implementation of multimode GI mPOFs as a part of communications and optical fiber sensory systems.

This study introduces a Fiber Specklegram Sensor (FSS) design for temperature measurement utilizing a single-multi-single mode optical fiber configuration. FSS technology offers unique advantages for potential development into portable sensing systems. This investigation explores an FSS design compatible with miniaturization by optimizing the interrogation system based on the relationship between speckle grain size and filtering fiber area. Temperature variations are detected through fluctuations in optical power at the sensor output, offering a simple and reduced interrogation scheme. The performance of the FSS is assessed through post-calibration measurements compared to a commercial Fiber Bragg Grating (FBG) sensor, demonstrating comparable results. These findings pave the way for compact and portable fiber optic temperature sensing systems leveraging FSS advantages while maintaining compatibility with established fiber optic measurements.

“…In recent years, optical fiber sensors have been widely used because of their unique advantages such as anti-electromagnetic interference [1][2], high sensitivity [3][4], corrosion resistance [5] and so on. Optical fiber sensors have been widely used in the measurement of liquid PH [6], stress [7], ion concentration [8], liquid level [9] and other physical quantities. Among them, liquid level measurement plays an important role in fuel storage [10][11], marine survey and farmland irrigation.…”

In this paper, a flexible optical fiber for two-parameter measurement of liquid level and temperature is presented. The flexible fiber is composed of polyurethane membrane and spherical microfiber few mode fiber (FMF) . It has excellent mechanical properties and thermal stability. By converting the change of liquid level into the change of static liquid pressure of polyurethane diaphragm, the performance of the sensor is analyzed by finite element method (FEM) and beam propagation method (BPM). The sensitivity of the liquid level sensor is 0.54534 nm/mm, and the sensitivity of the liquid level sensor is increased about 5 times. In order to eliminate the temperature interference, the temperature decoupling scheme is studied in this paper. The problem of cross sensitivity is solved by discussing the interference of temperature on double wave peaks. It has a broad prospect in the field of fuel level monitoring and control.
