“…LPFGs have been arc-induced in different types of fibers including Ge-free fibers [24,50,51], photonic crystal fibers [52][53][54][55][56][57][58], flat cladding fibers [59], and cladding-etched fibers [14,60,61] and in adiabatic tapers [62]. Modifications to the technique include applying no tension, applying compression, or even pressurizing the hollow core fibers during the arc discharges [5,19,55,63].…”

Long period fiber gratings produced by the electric arc technique have found an increasing interest by the scientific community due to their ease to fabricate, virtually enabling the inscription in any kind of fiber, low cost, and flexibility. In 2005 we have presented the first review on this subject. Since then, important achievements have been reached such as the identification of the mechanisms responsible for gratings formation, the type of symmetry, the conditions to increase fabrication reproducibility, and their inscription in the turning points with grating periods below 200 μm. Several interesting applications in the sensing area, including those sensors working in reflection, have been demonstrated and others are expected, namely, related to the monitoring of extreme temperatures, cryogenic and high temperatures, and high sensitivity refractometric sensors resulting from combining arc-induced gratings in the turning points and the deposition of thin films in the transition region. Therefore, due to its pertinence, in this paper we review the main achievements obtained concerning arc-induced long period fiber gratings, with special focus on the past ten years.

“…The highly birefringent photonic crystal fiber was fabricated with pure silica by the stack-and-draw method. 13,18,19) First, we stacked a number of silica rods into a hexagonal structure and then replaced the inner three layers of silica rods with the same number of silica capillaries. After this step, two large air holes were formed by replacing fourteen silica rods with two silica tubes having larger inner diameters on both sides of the three layers of silica capillaries.…”

We demonstrate a curvature sensor with a newly designed photonic crystal fiber of high birefringence (Hi-Bi PCF). The proposed PCF has two large air holes in the outer cladding region that give rise to core ellipticity during the fabrication process. The curvature sensor is based on the PCF Sagnac interferometer, the output spectrum shift of which provides information on the PCF curvature. It turns out that the curvature sensitivity depends on the bending directions with respect to the large-air-hole alignment. For the two orthogonal bending directions, the curvature sensitivities near 1480 nm are -1.87 nm/m-1 (parallel to the axis of the two large air holes) and 1.24 nm/m-1 (perpendicular to the axis of the two large air holes), respectively, and are also insensitive to environmental temperature variation. The proposed curvature sensor may be useful in thin structural deflection measurement.

“…Since its emergence, the photonic crystal fiber (PCF) 1) has not only created a new genre of study in fiber optics but has led the existing optical components to new applications in the fiber-optic industry. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] In recent years, D-shaped PCFs have attracted great research interest because they allow broadband operation in their specific applications. [17][18][19][20][21] Typically, the D-shaped optical fiber has been fabricated by burying a fiber in a grooved quartz block and then grinding the cladding to a thickness of a few microns, causing a range of materials overlaid on the polished cladding window to interact with an evanescent field of light propagating through the core.…”

We present a method for determining crystallographic symmetry axes in an air-hole structure of a photonic crystal fiber (PCF) with a hexagonal structure. This method is based on the measurement of intensity distribution of the light transversely scattered from the PCF. The symmetry axes can be determined from the distinctive intensity pattern that is repeated for an axial rotation of the PCF. Simulations and experimental studies reveal that the technique is reliable and quite sensitive to the angle between the crystallographic symmetry axis and the launched light.
