“…Moreover, the RIE phenomenon has been employed for the development of several dosimeter configurations based on radio-and thermo-luminesce effect [33][34][35][36][37]. Afterwards, many studies and reviews also targeted Fiber Bragg Grating (FBG) sensors written in several optical fibers by different techniques and irradiated under different conditions [38][39][40][41][42][43][44][45][46][47].…”

Over the last years, fiber optic sensors have been increasingly applied for applications in environments with a high level of radiation as an alternative to electrical sensors, due to their: high immunity, high multiplexing and long-distance monitoring capability. In order to assess the feasibility of their use, investigations on optical materials and fiber optic sensors have been focusing on their response depending on radiation type, absorbed dose, dose rate, temperature and so on. In this context, this paper presents a comprehensive review of the results achieved over the last twenty years concerning the irradiation of in-fiber Long Period Gratings (LPGs). The topic is approached from the point of view of the optical engineers engaged in the design, development and testing of these devices, by focusing the attention on the fiber type, grating fabrication technique and properties, irradiation parameters and performed analysis. The aim is to provide a detailed review concerning the state of the art and to outline the future research trends.

“…The reason behind choosing Si material is that the refractive index of Si changes below (5 × 10 -5 ) at (Dγ = 1000 kGy). Also, the thermo-optic coefficient of Si is equal (2.3 × 10 -4 ) at (Dγ = 66.5 kGy, and 32 °C) (Baccini, et al 2019;Cocorullo et al 2002). And the maximum rise in the temperature of Si is equal to (3.2 °C) due to the radiation effect.…”

“…Radiation dosimetry is the main point of much research due to the use of radiation in various applications (Baccini, et al 2019;Andreo, et al 2017). A dosimeter is any instrument that can produce an output value that represents the average absorbed dose deposited in its sensitive volume by ionizing radiation (Baccini, et al 2019;Chu, et al 2008). What's needed is a system that's simple to be used and set up, and that can detect radiation in real-time and from far distances.…”

“…The third type is based on varying the frequency of the Brillouin scattering in the distributed optical fibers (Alasia, et al 2005). The final type is based on photonic crystal fiber and Bragg gratings structures (Baccini, et al 2019). Photonic crystals (PhCs) have recently gained prominence in a variety of applications such as optical fibers, sensors, and biomedical devices (Entezam et al 2016;Elsayed et al 2021;Sayed et al 2022).…”

One-dimentional periodic structure infiltrated by (PVA/CV + CF)-polymer for high-performance sensitivity

et al. 2022

In the current work, we demonstrate a design to act as a Gamma-ray radiation dosimeter based on the one-dimensional photonic crystal (1D-PhC). The basic concept of the present dosimeter is based on a Porous Silicon (PSi) infiltrated by poly-vinyl alcohol (PVA)-polymer doped with crystal violet (CV) and carbol-fuchsine (CF) dyes. The mechanism of suggested dosimeter is based on the shift of the photonic bandgap (PBG) to higher wavelengths as exposed to gamma-ray radiation doses from 0 to 70 Gray (Gy). The basic axes of the current theoretical treatment are the transfers matrix method (TMM), Bruggeman's effective medium equation, and the fitted experimental data to the refractive index of the doped PVA-Polymer. The obtained results showed the proposed sensor is characterized by high stable sensitivity varied from (178–186 nm/ RIU) along an applied γ-dose from (10–70 Gy) in the visible range. In addition, we compared these results with previous researches. In addition, based on the our knowledge may be it is the first time that a 1D-PhC has been used for gamma-ray detection by using (PVA/CV + CF) based on Porous Silicon.

“…10–12 Also, some dosimeters rely on changes in the optical fiber and use spectrophotometry to measure the change in Radiation-Induced Attenuation (RIA). 8,13 Moreover, quartz fiber electroscope (QFE) dosimeters, electronic and electrical dosimeters, and film/badge personal dosimeters represent one of the most popular types. However, most of the aforementioned types have some disadvantages that appear in the form of limited shelf life, expensive price, temperature and light impacts that cause fading, and sensitivity to hard handling.…”
