Fiber Interferometers Based on Low Loss Fusion Splicing of Photonic Crystal FibersWe report temperature and strain sensing characteristics of two kinds of in-line fiber interferometers. One interferometer consists of a section of Hollow Optical Fiber(HOF) spliced between two Photonic Bandgap Fibers(PBGF) and the other is built by splicing a section of HOF between two Large Mode Area-Photonic Crystal Fibers(LMA-PCF). To minimize the splice losses, we carefully optimized the heating time and arc current of the splicer so as not to collapse the air holes of the fiber. It is found that the first interferometer has a temperature sensitivity of 15.4 pm/℃ and a strain sensitivity of 0.24 pm/με. The other interferometer exhibits a temperature sensitivity of 17.4 pm/℃ and a strain sensitivity of 0.2 pm/με.

“…Figure 1(a) shows the scanning electron microscope (SEM) image of the PCF which is composed of two large circular air holes in the outside of cladding region. The PS-PCF was fabricated with the stack-and-draw process [6]. The small air holes in the inner cladding and two large air holes in the outer cladding region are 0.73 μm and 11.7 μm in diameter, respectively.…”

Discrimination of chemical vapor and temperature effects by using a polarization-maintaining photonic crystal fiber interferometer

et al. 2012

View full text Add to dashboard Cite

A reflection-type interferometer based on a polarization-maintaining photonic crystal fiber (PM-PCF) is investigated for simultaneous measurement of chemical vapor and temperature. The PM-PCF with a length of 2.6 cm is fusion-spliced to standard single-mode fiber and airholes of the PM-PCF are fully collapsed allowing the excitation of different core and cladding modes in the PM-PCF corresponding to two orthogonal polarization modes. Since airholes at the end of the PM-PCF interferometer are left open, a chemical vapor can be infiltrated into the voids. Different sensitivities corresponding to input polarization states are utilized for discrimination between chemical vapor and temperature effects.

“…Well-matured technology is now developed in telecommunication and signal processing applications, metrology, instrumentation, medical surgery and imaging spectroscopy [3]. Some of the unusual and exciting characteristics that have revolutionized the light-guiding features of PCFs are highbirefringence [4][5][6][7][8][9][10][11][12][13][14][15], endlessly single-mode operation [16], high effective nonlinearity [17] and tailoring of Group Velocity Dispersion (GVD) [18]. Essentially these characteristics dictate most of today's fiber-based device applications, in particular the nonlinear fiber devices.…”

“…This property, when combined with a large anisotropic geometry, will produce a huge amount of birefringence. For this purpose of anisotropy geometry, several approaches have been followed such as altering the associated structural parameters namely, asymmetric core [10], elliptical air-holes [9], different sized air-holes [5,13] and air-holes filling with selective liquids along one of their diagonals [11,15]. Out of the above methods, asymmetric core PCF is the most studied one.…”

In this work, we report detailed numerical analysis of the near-elliptic core index-guiding triangularlattice and square-lattice photonic crystal fiber (PCFs); where we numerically characterize the birefringence, single mode, cut-off behavior and group velocity dispersion and effective area properties. By varying geometry and examining the modal field profile we find that for the same relative values of d/, triangular-lattice PCFs show higher birefringence whereas the square-lattice PCFs show a wider range of single-mode operation. Square-lattice PCF was found to be endlessly single-mode for higher air-filling fraction (d/). Dispersion comparison between the two structures reveal that we need smaller lengths of triangular-lattice PCF for dispersion compensation whereas PCFs with square-lattice with nearer relative dispersion slope (RDS) can better compensate the broadband dispersion. Square-lattice PCFs show zero dispersion wavelength (ZDW) red-shifted, making it preferable for mid-IR supercontinuum generation (SCG) with highly non-linear chalcogenide material. Square-lattice PCFs show higher dispersion slope that leads to compression of the broadband, thus accumulating more power in the pulse. On the other hand, triangular-lattice PCF with flat dispersion profile can generate broader SCG. Square-lattice PCF with low Group Velocity Dispersion (GVD) at the anomalous dispersion corresponds to higher dispersion length (L D ) and higher degree of solitonic interaction. The effective area of square-lattice PCF is always greater than its triangular-lattice counterpart making it better suited for high power applications. We have also performed a comparison of the dispersion properties of between the symmetric-core and asymmetric-core triangular-lattice PCF. While we need smaller length of symmetric-core PCF for dispersion compensation, broadband dispersion compensation can be performed with asymmetric-core PCF. Mid-Infrared (IR) SCG can be better performed with asymmetric core PCF with compressed and high power pulse, while wider range of SCG can be performed with symmetric core PCF. Thus, this study will be extremely useful for designing/realizing fiber towards a custom application around these characteristics.
