“…1(c), we can know that the air holes of the PCF have slight collapse. However, the collapse of air holes will increase the mode field diameter and make the energy between the two modes of interference more balanced, which is more conducive to the formation of interference and increase the contrast of spectral fringes [20,21]. A light source and an optical spectrum analyzer are connected to monitor the spectrum change during the fabrication.…”

A high sensitive refractive index sensor based on the cladding etched photonic crystal fiber (PCF) Mach-Zehnder interferometer (MZI) is proposed, which is spliced a section of photonic crystal fiber between two single modes fibers (SMFs).The interference fringe of the MZI shifts with the variation of the ambient refractive index (RI). It is found that the RI sensitivity slightly decrease with an increase in the interference length. The sensitivities of MZI with 35 mm PCF, 40 mm PCF, and 45 mm PCF are 106.19 nm/RIU, 93.33 nm/RIU, and 73.64 nm/RIU, respectively, in the range of 1.333 to 1.381. After etched, the RI sensitivity of the MZI could be improved obviously. The RI sensitivities of the MZI with 35 mm PCF are up to 211.53 nm/RIU and 359.37 nm/RIU when the cladding diameter decreases to 112 μm and 91 μm, respectively. Moreover, the sensor is insensitive to temperature, and the measured sensitivity is only 9.21 pm/ with the range from 20 ℃ to 500 ℃. In ℃ addition, the sensor has advantage of simple fabrication, low cost, and high RI sensitivity.

“…In the splicing process, the important parameters affecting the performance and the properties of the MZI are listed as the length of the DC‐PCF, the offset of the joint to the central axis of arc discharge, and the discharge arc conditions for fusion splicing . The first one condition was quantitatively under control; however, the last two were not.…”

A novel strain sensor was proposed by splicing a dual‐core photonic crystal fiber (DC‐PCF) with two single‐mode fibers. Owning to the mode index difference between the two fiber cores of DC‐PCF, a Mach‐Zehnder interferometer (MZI) pattern was achieved and its transmission spectrum is sensitive to the microstress of the DC‐PCF. We analyze the stress characteristics of the fiber sensor with different lengths of DC‐PCF. It shows that transmission spectrum pattern of the MZI shifts to the long wavelength with a sensitivity about 1.4pm/µε (for a 2‐cm DC‐PCF) and 1.9pm/µε (for a 4‐cm DC‐PCF) under an axial microstress. © 2014 Wiley Periodicals, Inc.

“…Several methods have been developed. A method of splicing between a PCF and a SMF, where nitrogen gas (N2) is pumped into the air holes of the PCF during fusion discharge to help reduce the splice loss was presented [11]. The offset splicing method where the offset between the joint and the central axis of the arc discharge was applied was done too [12] [13] [14].…”

Preparation of optical frequency references based on gas filled hollow core photonics crystal fibers

This work is oriented towards our research in the field of splicing and ending of optical frequency references based on hollow core photonics crystal fibers (HC-PCF). This type of references is very promising optical element to replacing classic bulky absorption cells for laser frequency stabilization. We prepared and present methods of splicing HC-PCF to standard telecommunication fiber by a fiber splicer. A special care was taken to optimize the splicer setting and to find and obtain a splice with minimal optical losses between HC-PCF and SMF. The manufactured fiber cell was closed at one side by connecting to SMF and second fiber end was prepared for placing into the vacuum chamber with the help of vacuum-tightened connection to be used as a optical frequency reference based on the acetylene gas for frequency stabilization of the laser standards.
