We report characterization results for our new silicon photonic chip for high-speed data transmission, called COTTONTAIL (Chip for detector instrumentation with wavelength division multiplex). Modulation bandwidths of different conventional and radiation-hardened travelling-wave Mach-Zehnder modulators are sufficient for very high data transmission rates. Wavelength filters for wavelength...
The increasing luminosity in CERN experiments enabled by future upgrades demands optical links with enhanced bandwidth and radiation tolerance. Silicon Photonics (SiPh) emerges as the optoelectronic technology meeting these requirements and is being considered for the next generation of optical readout systems of CERN detectors. We present the progress on Silicon Photonics for High Energy...
This study details the experimental characterization of silicon photonic ring modulators (RMs) and silicon-germanium (SiGe) electro-absorption modulators (EAMs) exposed to 12 MGy(SiO2) total ionizing dose (TID) within INFN’s project FALAPHEL. We extensively report on the evolution of their key performance metrics as a function of TID. These trends are analyzed in relation to the...
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. In order to manage the increased volume of data with the existing infrastructure, the proposed Coarse Wavelength...
