Silicon photonics is one of the technologies being investigated for future data transmission applications in High Energy Physics. A silicon photonics circuit, with its remote laser source, multi-channel integration potential and material compatibility with Si sensors and electronic circuits, could be of interest to HL-LHC applications and beyond if its components were found to withstand high levels of radiation. This seminar will summarize our recent investigations into the potential for using silicon-based Mach-Zehnder modulators in the harshest radiation environments of the HL-LHC.
We will present a simulation that has been developed to predict the effects of ionizing radiation on silicon modulators and demonstrate how the simulations were used to aid in our first in-house design of a silicon photonics chip. The chip was used to explore how the radiation resistance of a device is affected by various design parameters. We will present the results from our first measurements on our design and outline what we think the future holds for silicon photonics optical links at CERN.
