About the Role
Xanadu is seeking a Senior Photonics Design Engineer to drive the design and scaling of state-of-the-art passive and active components for fault-tolerant quantum hardware. You will develop and execute novel component design strategies to achieve unprecedented sub-milli-dB loss targets, engaging with fabrication, tooling, and test teams to manage trade-offs and close the design loop from concept to high-volume production.
Responsibilities
- Drive the design and scaling of state-of-the-art passive and active components powering Xanadu’s future fault-tolerant quantum hardware.
- Develop and execute novel component design strategies to achieve unprecedented sub-milli-dB loss targets.
- Engage with Fabrication, Tooling and Test teams to manage complex performance trade-offs.
- Execute sophisticated DOEs.
- Deploy data-driven analysis to close the design loop from initial concept to high-volume wafer production.
- Perform electro-optic co-design of active devices such as phase shifters and photodiodes with TIAs and electrical drivers.
Requirements
- Msc or PhD in Engineering, Science, or related field, with 2+ years experience in an industrial setting.
- Expert-level knowledge and experience designing passive integrated optical components including the incorporation of wafer variation.
- Detailed understanding of sources of loss in photonic devices and their relation to fabrication processes.
- Understanding of the tradeoff between different simulation approaches including sources of error and computational resource use.
- Deep experience with scripted photonic mask design and layout.
- Participated in 5+ tapeouts covering design, layout and analysis.
- Experience working in a collaborative team-based development environment, using version control systems such as git.
- Ability to operate in a fast-paced environment and manage multiple competing priorities.
- Expert-level knowledge and experience in designing active integrated optical components such as Pockels effect based phase shifters, or III-V photodiodes.
- Deep theoretical understanding of coupled mode interactions in the context of waveguides, resonators and nonlinear optics.
- Experience in developing components and performing tapeouts with photonic foundries.
- Turned designs into version controlled building blocks.
- Understanding of the concepts of “Design of Experiments” and “Design Centering” applied to wafer level optimization of photonic components.
- Performed statistical analysis on wafer level data using tools like JMP.
- Experience developing automated optimization approaches, such as particle swarm, bayesian and adjoint method.
- Incorporation of fabrication processes effects such as lithographic rounding, OPC/bias correction and material non uniformity into component optimization.
- Experience in developing design rule checks (DRC) and layout vs schematics (LVS) scripts.
- Experience in developing custom filler patterns and mask data preparation.
