“…The macroscopic effects of radiation on the performance of optical fibers are specifically evident in three aspects: (1) radiation-induced attenuation (RIA), which affects the fibers' transmission performance [51][52][53][54][55]; (2) radiation-induced emission (RIE), characterized by increased noise during fiber transmission, primarily observed when RIA is minimal [56,57]; and (3) influence on their optical and mechanical properties. The impact on the optical properties mainly manifests in changes to the fiber's refractive index after irradiation.…”

In recent years, optical fibers have found extensive use in special environments, including high-energy radiation scenarios like nuclear explosion diagnostics and reactor monitoring. However, radiation exposure, such as X-rays, gamma rays, and neutrons, can compromise fiber safety and reliability. Consequently, researchers worldwide are focusing on radiation-resistant fiber optic technology. This paper examines optical fiber radiation damage mechanisms, encompassing ionization damage, displacement damage, and defect centers. It also surveys the current research on radiation-resistant fiber optic design, including doping and manufacturing process improvements. Ultimately, it summarizes the effectiveness of various approaches and forecasts the future of radiation-resistant optical fibers.

“…Today, another use of OTDR based-systems is under qualification at CERN, in view of its deployment at the LHC [249,264]. • OFDR temperature sensors: for temperature sensing, the OFDR sensors associated with radiation-hardened optical fibers are able to operate up to very high doses of γ-rays [258,259,265] and neutron fluences up to 10 17 n cm -2 [17]. • OFDR liquid level sensor: in the context of post-Fukushima research, recent architecture for a water-level sensor to be implemented in nuclear pools has been demonstrated in [266] allowing the liquid level to be measured with a spatial resolution better than 1 cm or 3 cm in targeted normal and accidental conditions, respectively.…”

In this topical review, the recent progress on radiation-hardened fiber-based technologies is detailed, focusing on examples for space applications. In the first part of the review, we introduce the operational principles of the various fiber-based technologies considered for use in radiation environments: passive optical fibers for data links, diagnostics, active optical fibers for amplifiers and laser sources as well as the different classes of point and distributed fiber sensors: gyroscopes, Bragg gratings, Rayleigh, Raman or Brillouin-based distributed sensors. Second, we describe the state of the art regarding our knowledge of radiation effects on the performance of these devices, from the microscopic effects observed in the amorphous silica glass used to design fiber cores and cladding, to the macroscopic response of fiber-based devices and systems. Third, we present the recent advances regarding the hardening (improvement of the radiation tolerance) of these technologies acting on the material, device or system levels. From the review, the potential of fiber-based technologies for operation in radiation environments is demonstrated and the future challenges to be overcome in the coming years are presented.

“…The application of air-core PCFs is still limited by the reliability, the splicing with other fibers, high costs, and high transmission loss. [4,5] Compared to air-core PCFs, solid-core PCFs are easier to handle and exhibit lower attenuation. [6] Furthermore, most solid-core PCFs are made with pure silica, which is known to be radiation-hardened under gamma-ray radiation.…”

We investigated the steady state gamma-ray radiation response of pure-silica-core photonic crystal fibers (PSC-PCFs) under an accumulated dose of 500 Gy and a dose rate of 2.38 Gy/min. The radiation-induced attenuation (RIA) spectra in the near-infrared region from 800 nm to 1700 nm were obtained. We find that the RIA at 1550 nm is related with hydroxyl (OH − ) absorption defects in addition to the identified self-trapped hole (STH) defects. Moreover, it is proposed and demonstrated that reduced OH − absorption defects can decrease the RIA at 1550 nm. The RIA at 1550 nm has effectively declined from 27.7 dB/km to 3.0 dB/km through fabrication improvement. Preliminary explanations based on the unique fabrication processes were given to interpret the RIA characteristics of PSC-PCFs. The results show that the PSC-PCFs, which offer great advantages over conventional fibers, are promising and applicable to fiber sensors in harsh environments.
