Join to apply for the
STAFF Optical System Engineer
role at
Lumentum We're committed to bringing passion and customer focus to the business. If you like wild growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us! Job Description 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, 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. Skills & Experiences Familiarity with direct-detection and coherent optical communication architectures. Experience in modeling optoelectronic components (e.g., lasers, modulators, photodiodes, DAC, ADC, driver, TIA) 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 on common impairments in high-speed optical links. Hands-on experience with high-speed optical component measurements using oscilloscopes, spectrum analyzers, and other relevant equipment. Pay Range : $108,800.00 - $155,400.00 Disclaimer : Final base salary for the successful candidate will depend on multiple factors, including but not limited to, job location, where work will be performed, qualifications, work history and relevant experience.
