NUMERICAL SIMULATION METHODS APPLIED AT FIBER GRATING SENSORS DESIGN

Fiber Optic Sensor Design and Fabrication Methods

This Special Issue focuses on the innovative design of optical fiber sensor structures, including fiber Bragg gratings, long-period gratings, interferometric sensors, and advanced micro-structured fibers. Optical fiber sensors are devices that use optical fibers to detect and measure various parameters such as temperature, pressure, strain, and refractive index. The apparatus includes a heating source (110) and a robotic articulate arm (130) that may modify the geometry of an optical fiber (150). Nowadays fiber optic refractive index sensors are widely used in various fields such as chemical, biochemical, and in an industry field. The optical fibre can be used as a distributed sensor by exploiting light scattering effects or as a quasi-distributed sensor network by functionalizing the fibre through Bragg gratings photo-inscription for instance.

Simulation of Fiber Bragg Grating Temperature Variation

In this study, the behavior of FBGs under varying temperatures is modeled using Coupled Mode Theory (CMT), which provides an analytical framework for the coupling of forward and backward propagating modes within a periodic refractive index structure. It should be noted that temperature and strain sensitivities must be considered, when high performance of the optimal sensor is required. In this topic, we demonstrate how to simulate fiber Bragg grating (FBGs) using MODE'. 5, and a periodic variation of 1e-3 in the refractive index of the core of a step-index fiber. The optical properties of FBG and LPG are firstly analyzed and, consequently, the basics of simulation models are provided.

Fiber Bragg Grating Etching Methods

Sensitivity and mechanical properties are the key factors that affect the performance of strain-sensitive etched fiber Bragg grating (EFBG) sensors.

Embedded Design of Fiber Optic Sensors

This work proposes a novel method of embedding FOSs using capillaries within solid structures and investigates fiber positions and orientation uncertainties within capillaries of different sizes and their influences on strain measurement accuracies. Embedding fiber optic sensors (FOSs) within parts for strain measurement is attracting widespread interest due to its great potential in the field of structural health monitoring (SHM). Therefore, the purpose of this effort is to bridge the gap between civil engineering and sensor engineering communities through an overview on the up-to-date technological advances in both sectors, with a special focus on textile reinforced concrete embedded with fiber optic sensors.

Applications of German Fiber Optic Sensors

Recent progress and the state of the art of optical fiber sensing in Germany are demonstrated by examples of advanced fiber Bragg grating and distributed sensor system applications, fiber gyroscopes and other interferometric sensors, chemical and bio-medical. A fiber optic sensor and two fiber optics made of plastic or glass fibers make up a fiber optic system. The sensor contains a light source (transmitter), typically an LED, and a photodiode (receiver). Using fiber-integrated beam steering and shaping, individual sensors up to a diameter of 80 microns can be manufactured.
