We investigated in situ the temperature influence on the Radiation-lnduced Attenuation (RIA) of an Al-doped single-mode optical fiber in the Visible and Near-lnfraRed spectral regions (400 nm - 2 µm, room temperature to 300°C).

We investigated how the photobleaching phenomenon could help in reducing the radiation impact on the performances of backup Erbium Doped Fiber Amplifiers (EDFAs) and Erbium­-Ytterbium Doped Fiber Amplifiers (EYDFA) .

Electrical characterizations of T2SL IR photodetectors under 60 MeV proton fluence up to 8x1011 cm-2 were performed. Dark current increases with increasing the DDD independently of the cut-off wavelength and the number of T2SL periods.

Irradiation effects are studied on commercial lnGaAs image sensors with hybrid direct Cu-Cu bonding. Performances, dark current and random telegraph signal are measured after 62MeV proton tests with different doses; and compared to existing models.

Dark-Current Random Telegraph signal is studied after proton irradiation in new scale silicon micro-volumes using a commercial CMOS Image Sensor. State-of-the-art empirical trends and new scale effects are discussed.

Two popular types of Silicon Photonics modulators have been exposed to ionizing radiation up to 4 MGy. Ring Modulators are shown to be the most tolerant, showing no degradation in performance up to these levels.

We performed at TRIUMF in-situ radiation induced attenuation measurements caused by protons in bulk optical glasses and compared them with gamma-rays effect. We used GEANT4 calculations to compute the right deposited for each glass.
