The consolidation of the Large Hadron Collider (LHC) Beam Instrumentation requires the digitisation of the analogue signals from the detectors within the radiation areas. Subsequently, the digital data are transmitted via the existing fibre plant to the back-end area for processing. [...]

The increasing luminosity in CERN experiments, enabled by future upgrades, demands optical links with enhanced bandwidth and radiation tolerance. Silicon Photonics (SiPh) has emerged as the optoelectronic technology meeting these requirements and is being considered for the next generation of optical readout systems for CERN detectors. [...]

Thermal annealing in silicon photonics ring modulators
/ Lalović, M (Belgrade, Inst. Phys. ; CERN) ; Detraz, S (CERN) ; Marcon, L (CERN) ; Olanterä, L (CERN) ; Prousalidi, T (CERN ; Natl. Tech. U., Athens) ; Sandven, U (CERN) ; Scarcella, C (CERN) ; Sigaud, C (CERN) ; Soós, C (CERN) ; Troska, J (CERN)
Silicon photonics technology promises significant improvements for fibre optic links of future upgrades of HEP experiments. Such systems will require high levels of radiation tolerance and silicon photonics modulators have been shown to be very robust when exposed to high levels of radiation under certain conditions.

Effects of High Fluence Particle Irradiation on Germanium-on-Silicon Photodiodes
/ Olanterä, Lauri (CERN) ; Scarcella, Carmelo (CERN) ; Lalović, Milana (CERN ; Belgrade U.) ; Détraz, Stéphane (CERN) ; Pandey, Awanish (CERN) ; Prousalidi, Theoni (CERN ; Natl. Tech. U., Athens) ; Sandven, Ulrik (CERN) ; Sigaud, Christophe (CERN) ; Soós, Csaba (CERN) ; Troska, Jan (CERN)
Waveguide-Integrated Germanium-on-Silicon (Ge-on-Si) photodiodes are integral components in silicon photonics and understanding their radiation tolerance is important for applications that intend to use silicon photonics in harsh radiation environments. Here we report the results of high fluence particle irradiation tests on Ge-on-Si photodiodes. [...]

System Development of Radiation-Tolerant Silicon Photonics Transceivers for High Energy Physics Applications
/ Prousalidi, Theoni (CERN ; Natl. Tech. U., Athens) ; Scarcella, Carmelo (CERN) ; Ahmed, Aalia (CERN ; York U., England, Dept. Math.) ; Detraz, Stéphane (CERN) ; Lalović, Milana (Belgrade U.) ; Olanterä, Lauri (CERN) ; Pandey, Awanish (CERN) ; Sigaud, Christophe (CERN) ; Soós, Csaba (CERN) ; Troska, Jan (CERN) et al.
Silicon photonics enables the manufacturing of high-speed, low-power, integrated optical circuits with compact footprints, and recent studies have also shown it to have a high tolerance to radiation. The technology has, therefore, been identified as an excellent candidate for the development of the next generation of radiation-tolerant optical links for high-energy physics (HEP) experiments at CERN.

High speed radiation tolerant optical links based on coarse wavelength division multiplexing
/ Marcon, L (CERN) ; Scarcella, C (CERN) ; Detraz, S (CERN) ; Lalović, M (CERN ; Belgrade U.) ; Olantera, L (CERN) ; Prousalidi, T (CERN ; Natl. Tech. U., Athens) ; Sandven, U (CERN) ; Sigaud, C (CERN) ; Soós, C (CERN) ; Troska, J (CERN)
The upgrade of CERN’s accelerator complex requires improved beam instrumentation systems that will generate an increased volume of data to be transferred from the radiation areas to the back-end. A solution that increases the throughput of already deployed fibers, with minimal increase of the system complexity, consists in implementing the coarse wavelength division multiplexing (CWDM) technique where independent optical carriers at properly spaced wavelengths are multiplexed into a single fiber.

Abstract
The Versatile Link+ project targeting the Phase 2 HL-LHC detector upgrades is entering the production phase. After several years of prototyping, the industrialisation of the Versatile Link+ Transceiver (VTRx+) was launched in 2021 and the production is scheduled to start in 2022. [...]
