“…According to the calculated mode distributions, there are usually four states; they are the x-polarized even mode (x-EM) (Figure 2h); x-polarized odd mode (x-OM) (Figure 2i); y-polarized even mode (y-EM) (Figure 2j); and y-polarized odd mode (y-OM) (Figure 2k), respectively. Generally, the parity can be distinguished based on the direction of the arrow, while the even modes possess similar properties and both arrows point in the same direction, the odd modes have phase difference π between two cores with two arrows in opposite directions [33,34]. Both even and odd polarized modes perform resonance coupling with 2-SPP modes being investigated.…”

A hexagonal photonic crystal fiber (PCF) sensor with a dual optofluidic channel based on surface plasmon resonance (SPR) effect is proposed. The sensor characteristic is numerically explored by software integrated with the finite element method (FEM). The numerical results show that, when the analyte refractive index (RI) varies from 1.32 to 1.38, high linearity between resonance wavelength and analyte RI is obtained and the value of adjusted R2 is up to 0.9993. Simultaneously, the proposed sensor has maximum wavelength sensitivity (WS) of 5500 nm/RIU and maximum amplitude sensitivity (AS) of 150 RIU−1, with an RI resolution of 1.82 × 10−5 RIU. Besides, owing to a simple structure and good tolerance of the proposed sensor, it can be easily fabricated by means of existing technology. The proposed sensor suggests promising applications in oil detection, temperature measurement, water quality monitoring, bio-sensing, and food safety.

“…In this paper, a water-based MF with a particle volume concentration of 0.53 emu/g was used, and H c and T is assumed 43 Oe and 294 K, respectively. [15] Combining mode coupling theory and super-mode theory, [36] when the DCPCF is viewed as a monolithic waveguide, each mode in the waveguide will form two supermodes, namely the symmetric mode (y-even, x-even) and the asymmetric mode (y-odd, x-odd). The coupling law of DCPCF can be analyzed by the superposition of supermodes when the light with the energy of P in is input from the core C1.…”

“…[7,8] With the increasing application of optical fibers in modern optical systems, it is of great significance to study the polarization controllers based on optical fibers. At present, there have been many reports on the research of fiber PBS and fiber polarization filter, [9][10][11][12][13][14][15] but there are still some deficiencies in these reports. Firstly, the cost of introducing elliptical holes or inconsistent round holes to increase birefringence is that it will be a great challenge to fabricate fibers.…”

The research of high-performance polarization controllers is of great significance for expanding the application field of polarization optics. Here, a polarization switch is demonstrated by using a dual-core photonic crystal fiber (DCPCF) with four symmetrical air holes, placed above and below each core, filled with magnetic fluid (MF). The switch, which utilizes a magnetic field to change the coupling length ratio of the x and y polarization modes, enables dynamic tuning of the polarization state and extinction ratio. Numerical results show that when the working length is 36.638mm, the magneto-optical polarization switch can operate in four communication bands, i.e., 1509nm to 1520nm, 1544nm to 1556nm, 1578nm to 1591nm, and 1611nm to 1624nm. Moreover, the extinction ratio (ER) is greater than 20dB in the fiber length range of 38.5 mm to 38.7 mm, indicating that the device has a good fault tolerance for the interception of the fiber length.

A circular ultra-short As2S3 filled double-core photonic crystal fiber polarization beam splitter is proposed. The finite element method is used to study the performance of the designed photonic crystal fiber polarization beam splitter. By filling high refractive index As2S3 into the central air hole, the coupling performance of the double-core PCF is improved. By optimizing geometric parameters, the splitting length of the circular beam splitter can be as short as 72.43 μm, and the extinction ratio can reach −151.42 dB. The high extinction ratio makes the circular polarization beam splitter have a good beam splitting function. The designed circular double-core photonic crystal fiber has the same cladding pore diameter, which is easier to prepare than other photonic crystal fibers with complex pore structure. Due to the advantages of high extinction ratio, extremely short beam splitting function and simple structure, the designed polarization beam splitter will be widely used in all-optical networks and optical device preparation.
