“…Particularly when we focus on the center of the fiber core, the values of σ x and σ y are −0.37 MPa and −13. is K p = 195 rad/MPa/m, which is more than 4 times of that recently reported in [22]. Note that the value of σ y in the fiber core is almost 14 times of the value of the pressure utilized on the surface of the fiber cladding.…”

“…Thus, utilizing the FHF can achieve a resolution of several tens of Pa if the same setup is used. The polarimetric pressure sensitivity of the FHF with parameters of L = 2 µm, d = 2 µm, H = 8 µm, R = 71.25 µm, D = 300 µm is K p = 607 rad/MPa/m, which is more than 14 times of that for the recently reported MSF [22].…”

“…Side-hole fibers were proposed and demonstrated for pressure sensing [8][9][10][11][12]. More recently, several microstructured fibers (MSFs) (i.e., photonic crystal fibers (PCFs)) were also proposed for pressure sensing [13][14][15][16][17][18][19][20][21][22]. Thanks to the design flexibility of the cross-section, MSFs have achieved excellent properties in birefringence [23][24][25][26][27][28][29], dispersion [30][31][32][33][34], single polarization single mode [35][36][37], nonlinearity [38], and effective mode area [39][40][41] over the past several years.…”

Abstract-A highly birefringent four-hole fiber (FHF) with a pair of large air holes and a pair of small air holes are proposed for air/hydrostatic pressure sensing. The birefringence of the FHF can be up to 0.01 due to the rectangle-like fiber core surrounded by four air holes. Therefore, a FHF with a length of only several centimeters is required for high-sensitivity pressure sensing based on a Sagnac interferometer. Optical properties of the FHF such as effective index and birefringence are investigated. Pressure sensor based on the FHF depends on the pressure-induced refractive index change or pressureinduced birefringence. The stress distribution of the FHF subjected to an air/hydrostatic pressure is represented. Simulations show that the principal stress component parallel to the slow axis of the of the FHF under the air/hydrostatic pressure is greatly enhanced due to the existence of two large air holes, which consequently results in a high sensitivity of the FHF-based pressure sensor. Relationships between the pressure-induced birefirngence and the radius of the large air hole, the external diameter of the FHF, or the ellipticity of the elliptical FHF are investigated. The polarimetric pressure sensitivity of the FHF can be up to 607 rad/MPa/m.

“…Although strongly demanded, such splices are still one of the fundamen− tal issues for realistic PCF applications due to the completely different inner structure of SMFs and small core and/or large air filling factor PCFs which are considered for different appli− cations, such as gas and liquid spectroscopy [1], surface−plas− mon−resonance [2], nonlinear exploitation [3][4][5], sensors [6] including hybrid system PCFs air−holes filled with liquid crystal [7][8][9], fibre lasers [10] and others.…”

We report the methodology of effective low-loss fusion splicing a photonic crystal fibre (PCF) to itself as well as to a standard single mode fibre (SMF). Distinctly from other papers in this area, we report on the results for splicing suspended core (SC) PCF having tiny core and non-Gaussian shape of guided beam. We show that studied splices exhibit transmission losses strongly dispersive and non-reciprocal in view of light propagation direction. Achieved splicing losses, defined as larger decrease in transmitted optical power comparing both propagation directions, are equal to 2.71 ±0.25 dB, 1.55 ±0.25 dB at 1550 nm for fibre SC PCF spliced to itself and to SMF, respectively.

“…For example, pressure sensors using PM-PCF [7][8][9] have 5.44 times lower birefringence-pressure sensitivities than that of two-hole solid-core optical fibers. Thus, some research efforts were devoted to design PM-PCF with better pressure sensitivity [10,11].…”

Abstract:We present the design of an air hole microstructured photonic crystal fiber for pressure sensing applications. The air-hole photonic crystal lattices were designed to produce a large intrinsic birefringence of 1.16x10 -3 . The impact of the surrounding air holes for pressure sensing to the propagation mode profiles and indices were studied and improved, which ensures single mode propagation in the fiber core defined by the photonic crystal lattice. An air hole matrix and a practical chemical etching process during the fiber perform preparation stage is proposed to produce an optical fiber with a birefringence-pressure coefficient of 43.89x10 -6 MPa -1 or a fiber Bragg grating pressure responsivity of 44.15 pm/MPa, which is a 17 times improvement over previous photonic crystal fiber designs. 14.
