“…And the real part of the effective index of the core mode (Y-pol) and the SPP mode (Y-pol) are moving closer at shorter wavelengths toward the anti-crossing point, then slowly separated at longer wavelengths. The reason why the two resonance peaks are separated have been explained in our previous work [2]. In the following part, the coupling theory [27] will be employed to analysis the energy coupling between the core mode and the SPP mode.…”

We propose and investigate a photonic crystal fiber (PCF) refractive index sensor with triangular lattice and four large-size channels based on surface plasmon resonance. In such sensor, two gold wires obtained by chemical reaction are filled in two air holes between the upper and lower channels. Numerical results show that the refractive indexes of the analytes can be detected from 1.30 to 1.79. It's a very broad detection range that is rarely seen in the field of photonic crystal fiber sensor based on surface plasmon resonance. The average sensitivity of this photonic crystal fiber could be 100 nm/refractive index unit (RIU) in the dynamic index range from 1.30 to 1.63. In the range from 1.63 to 1.79, the highest sensitivity could reach to 3233 nm/RIU. The ability to integrate four largesize microfluidic channels for efficient analyte flow in is attractive for the development of integrated highly sensitive PCF-SPR sensors.

“…The energy on the metal surface will be increased; that is, the surface plasmon resonance (SPR) effect takes place [ 11 ]. The MOFs based on SPR play an important role in sensors [ 12 ], splitters [ 13 ], and polarization filters [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ], etc. Polarization effects play a key role in a wide range of polarization-sensitive optical fiber systems.…”

In this paper, a pentagonal microstructured optical fiber polarization filter by utilizing a surface plasmon resonance effect is proposed. The characteristics of the mode-coupling and filtering of the filter are studied by making use of the full-vector finite element method. The performance of the filter is greatly affected by the structure parameters. The losses of Y and X polarization of the fiber core are 665.97 and 0.17 dB/cm at 1.55 μm, respectively, and the loss ratio is 3917.47. This shows that the filter has a greater loss ratio. Moreover, both the extinction ratio and tolerance are also researched, which shows that the proposed filter has a wider filtering bandwidth and better fabrication tolerance. The designed filter has an important role in wavelength-division multiplexing (WDM) and coherent optical fiber communication systems.

“…Zhang [13] proposed a polarization filter based on PCF filled with gold wire; the resonance loss of x-pol mode could reach to 399 dB/cm at the communication wavelength 1550 nm. The polarization filters in [11][12][13] could just filter out polarized mode at one communication window of 1550 nm. Based on the above issues, we proposed a novel polarization filter based on PCF with two large-diameter gold-coated air holes which could filter out y-pol mode at the communication window of 1310 nm and x-pol mode at the communication window of 1550 nm by the same structure, the resonance losses of y-pol mode at the wavelength 1310 nm and x-pol mode at the wavelength 1550 nm could reach to 475 and 369 dB/cm, respectively.…”

A polarization filter at the two communication windows of 1310 and 1550 nm based on photonic crystal fiber (PCF) with two large-diameter gold-coated air holes is proposed. The effects of geometrical parameters of the PCF on the performances of polarization filter are evaluated by finite element method (FEM). Numerical simulations reveal that the polarization filter possesses ultra-short length of 1 mm and high extinction ratios of 396 and −292 dB at the communication wavelengths of 1310 and 1550 nm, respectively. The bandwidth of extinction ratio (ER) better than 20 dB is 181 nm at the communication window of 1310 nm. Moreover, the bandwidth of ER better than −20 dB is 423 nm at the communication window of 1550 nm.
