STAFF Optical System Engineer

Lumentum • Friendswood, TX

99d • $108,800 - $155,400

About The Position

Develop comprehensive end-to-end optical system models, including digital signal processing (DSP), drivers, transimpedance amplifiers (TIA), and optical components such as lasers, Mach-Zehnder modulators (MZMs), and photodetectors. Perform signal integrity analysis, including constellation diagram, eye diagram generation, and bit error rate (BER) simulations. Implement and simulate digital equalization techniques such as FFE, DFE, MLSD, and pre-emphasis for signal integrity optimization. Analyze the impact of various impairments on system performance, such as noise, crosstalk, non-linearity, and reflections. Conduct both numerical and analytical simulations to assess optical system behavior under realistic operating conditions. Correlate simulation models with experiment data at both module and device levels.

Requirements

• Familiarity with direct-detection and coherent optical communication architectures.
• Experience in modeling optoelectronic components using tools such as VPIphotonics, MATLAB, or Python.
• Familiarity with advanced DSP techniques, such as linear and decision-feedback equalization (FFE/DFE).
• Knowledge of modeling common impairments in high-speed optical links.
• Hands-on experience with high-speed optical component measurements using oscilloscopes, spectrum analyzers, and other relevant equipment.
