Performance of Sagnac Interferometer with Loops Made of PCF and PANDA Fibers

چکیده
Optical fiber Sagnac loop as a interferometer (SLI), is a useful component utilized in devices and systems of optical technology [1,2]. As of today, several components based on SLI, have been designed for applications of wavelength division multiplexing (WDM) filters and optical sensors, using conventional and photonic crystal fibers [3-6]. In an SLI, two interfering waves in an optical fiber loop counter-propagate in a similar path. Usually, a standard optical fiber Sagnac loop made of a birefringent fiber in a comparison to Mach-Zehnder interferometer has several advantages, such as insensitivity to temperature, high extinction ratio, and independent to input polarization of light waves [7].

In-line microfluidic refractometer based on C-shaped fiber assisted photonic crystal fiber Sagnac interferometer.
We propose and demonstrate a highly sensitive in-line photonic crystal fiber (PCF) microfluidic refractometer. Ultrathin C-shaped fibers are spliced in-between the PCF and standard single-mode fibers. The C-shaped fibers provide openings for liquid to flow in and out of the PCF. Based on a Sagnac interferometer, the refractive index (RI) response of the device is investigated theoretically and ...
متن کاملUncertainty of the Sagnac interferometer-based measurement of the modal birefringence of polarization maintaining optical fibers
Presented is an analysis of the expanded uncertainty of an indirect measurement of modal birefringence of polarization maintaining fibers, based on the Sagnac interferometer and an optical spectrum analyzer. By using this method it is easy to achieve an expanded measurement uncertainty considerably lower than 1%, at a confidence level of 0.95, in measurements of fibers, whose birefringence is i...
متن کاملPressure sensor realized with polarization-maintaining photonic crystal fiber-based Sagnac interferometer.
A novel intrinsic fiber optic pressure sensor realized with a polarization-maintaining photonic crystal fiber (PM-PCF) based Sagnac interferometer is proposed and demonstrated experimentally. A large wavelength-pressure coefficient of 3.42 nm/MPa was measured using a 58.4 cm long PM-PCF as the sensing element. Owing to the inherently low bending loss and thermal dependence of the PM-PCF, the pr...
متن کاملPhotonics Crystal Fiber Loop Mirrors and Their Applications
Fiber loop mirrors (FLMs), also called Sagnac interferometers, are interesting and very useful components for use in optical devices and systems [1, 2]. Many components based on FLMs have been demonstrated for applications in wavelength-division-multiplexing filters and in sensors, among others [3-7]. In FLM, the two interfering waves counter-propagate through the same fiber and are exposed to ...
متن کاملNumerical Analysis of Index-Guiding Photonic Crystal Fibers with Low Confinement Loss and Ultra-Flattened Dispersion by FDFD Method
In this article, perfectly matched layer (PML) for the boundary treatment and an efficient compact two dimensional finite-difference frequency-domain (2-D FDFD) method were combined to model photonic crystal fibers (PCF). For photonic crystal fibers, if we assume that the propagation constant along the propagation direction is fixed, three-dimensional hybrid guided modes can be calculated by us...
