About the job
Own end-to-end simulation, co-design, and lab verification of photonic-electronic links for Passage, from photonic device modeling through transceiver channel characterization.
What you'll do
- Develop link simulation models and analyze BER, link margins, process corners, and variation.
- Co-design photonic devices and analog circuits; develop link budgets and drive design improvements.
- Define lab test protocols and close the loop between simulations and silicon measurements.
What they ask for
- PhD in a relevant discipline and 5+ years of experience, or MS and 8 years of directly relevant industry experience.
- Expertise in photonic device physics and optical link design.
- Hands-on photonic simulation and analog/mixed-signal simulation experience.
- Experience with optical link budgets, corner analysis, simulation-to-measurement closure, high-speed lab characterization, and Python.
Nice to have
- Silicon photonics tape-out and post-silicon characterization experience.
- Exposure to CPO, NPO, or optical I/O chiplet integration.
