We are looking for a Photonics Design Engineer (Active Devices) with proven, hands-on experience designing, simulating, and measuring active
silicon-photonics components (e.g., modulators, phase shifters, photodiodes).
Responsibilities:
Design and model active Silicon Photonics devices; own specs, compact models,
and layout intent.
Drive design for manufacturability: analyze performance across
process/voltage/temperature corners and wafer variability; run Monte-Carlo/tolerance
studies.
Build scripted, parametric simulation flows (sweeps/optimization) and extract
figures of merit (EO S21, VπL, responsivity, dark current, bandwidth, IL).
Plan and execute lab/wafer-level measurements; close the mode-to-silicon loop
by comparing data to simulations and updating moels.
Collaborate with process, test, and packaging teams on masks, runsets, and
DFT/DFM reviews.
Requirements: M.Sc. (or higher) in Photonics, Electrical Engineering, Physics, Optoelectronics, or
related.
Hands-on with active optoelectronic devices is required: design + simulation and
measurement/characterization.
Solid grasp of photonic/device physics (e.g., carrier-depletion/thermal phase shifters,
PN/PIN modulators, Ge or III-V PDs).
Proficiency with FDTD/EME/mode solvers and circuit-level simulators; ability to
build/fit compact models.
Strong analytical/problem-solving skills; comfort with data analysis in Python/Matlab
and version control (git).
Clear communication; effective teamwork.
Preferred Skills:
Experience with SiPh PDKs, gdsfactory/KLayout, and DRM/DRC flows.
Circuit-/system-level simulation (e.g., INTERCONNECT/Caphe) and CML/compact-
model extraction.
Practical lab experience: high-speed EO/IV/OP measurements, fixture de-embed,
This position is open to all candidates.
