“…The Ge-doped fibers show the highest induced losses, as expected. There is remarkable difference in performance amongst the Ge-doped fibers from the various manufacturers and the RIA varies by as much as 40% in agreement with similar studies [23].…”

Abstract-This paper reports on the radiation induced attenuation of light at 1310 nm and 1550 nm in 12 commercially available single mode (SM) optical fibers. The fiber samples are exposed to gamma rays from a 60 Co source and to a high energy physics radiation field. The attenuation is studied as a function of total dose, dose rate, light power and temperature. Radiation hard fibers from one manufacturer show an extraordinary low attenuation for light at 1310 nm that does not exceed 5 dB/km even after a total dose of 1 MGy. 2500 km of this type of fiber have been produced by the manufacturer and quality assurance measurements of the production batches are presently ongoing.

“…All the optical link component types that will be used in the CMS tracker (InGaAsP/InP lasers, InGaAs p-i-n photodiodes, single-mode optical fibers and optical connectors) have been tested [6][7][8][9][10][11] with 60 Co photons and at least one heavy particle source, including 6MeV (average energy) neutrons (at ISN/SARA, Grenoble), 330MeV pions (at PSI, Villigen), and 24GeV protons (at CERN). These sources were chosen as the particle species and energies broadly represent the overall radiation spectrum that will be encountered inside the CMS Tracker [2,3].…”

Radiation damage in 1310nm InGaAsP/InP multi-quantum-well lasers caused by 0.8MeV neutrons is compared with the damage from other radiation sources, in terms of the increase in laser threshold current. The annealing behavior is then presented both in terms of both temperature and forward-bias current dependence. The annealing can be described by a model where radiation induced defects have a uniform distribution of activation energies for annealing. This model can then be used to predict the long-term damage expected for lasers operating inside the CMS tracker.

“…We consider the radiation-induced degradation in the fibers used to couple light into the DUTs to be negligible; previous studies (e.g., [10]) have shown radiation-induced attenuation in commercial SMF-28 fiber to be less than dB/m in radiation environments similar to those considered here, and in our measurement setups only a very small amount of fiber (much less than m) was placed in the area of high radiation.…”

High-speed Mach-Zehnder interferometer silicon modulators were irradiated with neutrons and X-rays in two separate radiation tests. The devices were exposed to a total fluence of neutrons/cm and a total ionizing dose of 1.3 MGy; levels comparable to the worst radiation levels for a tracking detector after 10 years of operation at the High-Luminosity LHC. Our measurements indicate that the devices' performance does not significantly degrade after exposure to nonionizing radiation and begins to be affected by ionizing radiation after a dose of a few hundred kGy; the phase-shift for an applied reverse bias of 1 V is 10% of its preirradiated value after 600 kGy of received ionizing dose.Index Terms-High-luminosity LHC (HL-LHC), optoelectronics, radiation damage, silicon photonics, total ionizing dose (TID).
