“…It consists of two layers: the core with a large diameter and the cladding with a small thickness. The common core material of this type of POF is PMMA with a larger RI, and the common cladding material of this type of POF is a fluorinated polymer with a lower RI [ 66 ]. This type of fiber can transmit a large number of modes, and it has been used in the sensing fields for a long time with the intensity demodulation method generally.…”

The simple and highly sensitive measurement of the refractive index (RI) of liquids is critical for designing the optical instruments and important in biochemical sensing applications. Intensity modulation-based polymer optical fiber (POF) RI sensors have a lot of advantages including low cost, easy fabrication and operation, good flexibility, and working in the visible wavelength. In this review, recent developments of the intensity modulation POF-based RI sensors are summarized. The materials of the POF and the working principle of intensity modulation are introduced briefly. Moreover, the RI sensing performance of POF sensors with different structures including tapered, bent, and side-polished structures, among others, are presented in detail. Finally, the sensing performance for different structures of POF-based RI sensors are compared and discussed.

“…Research on SDM transmission in MM SCFs has recently seen tremendous progress, with efficient solutions for signal multiplexing/de-multiplexing in MM fibers and integrated MM amplification. For example, every ADM channel inside the carrier MM SCF is assigned radially distributed, dedicated spatial positions in the case of SDM when using the same wavelength [10]. The launch angle and mode coupling strength determine where each channel is located inside the MM SCF.…”

“…The modelling of propagation and SDM in MM optical fibers is still a challenging task since until recently, commercial simulation software packages were not designed neither for MM SCFs nor MM MCFs. This deficiency has been addressed in our previous works for modeling a different types of conventional MM SCFs [10,13,15,17,18]. In this work, by numerically solving the TI PFE for varying widths of the launch beam distribution, we calculate the length at which the EMD and an SSD is attained in each of the seven cores of the MM MC SOF.…”

We analyze the effect of launch beam distribution on space-division multiplexing (SDM) performance in multimode multicore silica optical fibers (MM MC SOF) with seven cores. The time-independent power flow equation (TI PFE) is used to explore the effect of the width of the distribution of the Gaussian launch beam on power flow in each of the seven cores. We show that the optical fiber length at which the equilibrium mode distribution (EMD) and steady-state distribution (SSD) are obtained is greatly influenced by the width of the Gaussian launch beam distribution. We further show that when the width of the Gaussian launch beam distribution widens, the optical fiber length at which angular division multiplexing (ADM) in each of the seven cores can be realized with minimal crosstalk between neighboring angular optical channels decreases. We demonstrate that, for increasing the capacity of an optical fiber transmission system, an SDM system with two- and three-channel ADM and multicore optical fiber multiplexing can be implemented with the proposed seven-core MM MC SOF at optical fiber lengths up to ≈1 km (2 ADM channels × 7 cores) and ≈200 m (3 ADM channels × 7 cores), respectively. Such characterization of MM MC SOFs under various launch conditions is important for building a multicore optical fiber SDM transmission system.

“…In the earlier publications various accurate methods of multimode fibers modal analysis is exploited. For example, the method that relies on the solving power flow equations was described in [21][22][23][24]. The solution gives the angular properties of the beam that originates from a prescribed source distribution and propagates down the multimode fiber.…”

A fiber optic device sensitive to humidity is detailed and modelled by ray tracing based on Monte Carlo simulation. The device is intended primarily for monitoring humidity in the microenvironment of wounds without removing the wound dressing and thus disturbing the wound-healing process. To produce the sensor, cladding is removed from a segment of its polymer-fiber and mesoporous SiO2 nanoparticles are deposited in the exposed zone. This introduces an additional light-transmission loss. The extent of such loss is related to the relative humidity of the environment. Such a relationship, embodying the essence of the sensor’s modulation principle, is examined in this paper by ray tracing based on Monte Carlo simulation. The sensor is explained in detail and its performance is characterised.
