STAFF Optical System Engineer

It's fun to work in a company where people truly BELIEVE in what they're doing!
We're committed to bringing passion and customer focus to the business.

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.
