Full Job Description

Join CERN's detector R&D program for future high-energy physics experiments, working on advanced optical communication technologies for next-generation particle detectors. In this role, you will contribute to the development of radiation-tolerant Silicon Photonics components for high-speed data transmission in challenging environments. Your work will include hands-on laboratory characterisation of Silicon Photonics circuits and the design of innovative photonic devices. This position offers the opportunity to work at the intersection of photonics, electronics, and particle detection technologies. Your responsibilities * Contribute to the electro-optical characterisation of custom-designed photonic integrated circuits (PICs). * Validate the PIC measurement results against optical simulations. * Support the integration and evaluation of PICs with particle readout chips (ROCs). * Prototype and demonstrate coarse wavelength-division multiplexing (CWDM) data-transmission systems. * Characterise and benchmark different data-link architectures. * Simulate and design a new generation of test PICs based on measurement results from existing PICs. * Present the progress to project meetings and conferences. * Document measurement and simulation results and methods. Your profile * Proven experience in design and simulation of photonic components and integrated photonic circuits. * Experience in laboratory characterisation of optical and photonic components using OSAs, tunable lasers, and power meters. * Proven experience in high-speed electro-optical measurements utilising pattern generators, oscilloscopes, error detectors, VNAs, and spectrum analysers. * Hands-on experience in automation of measurement setups for opto-electronic devices. * Extended experience in analysis and interpretation of experimental and measurement data. Skills * Expert user of photonic simulation tools (e.g., Ansys Lumerical, Synopsys RSoft). * Proficient user of electronic and optical laboratory instrum
