Senior Laser & SOA Characterization Engineer at Lightmatter | LAYIQ

Lead hands-on characterization of semiconductor lasers, tunable laser sources, DFB lasers, DBR/ECL lasers, laser diodes, and semiconductor optical amplifiers.
Measure and analyze key laser and SOA performance metrics, including output power, wavelength, optical spectrum, SMSR, RIN, linewidth, gain, saturation power, ASE, noise figure, tuning behavior, optical stability, wavelength stability, and thermal sensitivity.
Develop advanced LIV, L-I-V-T, wavelength tuning, power stability, RIN, SMSR, linewidth, and long-term drift measurement methodologies.
Characterize devices across current, voltage, temperature, optical loading, polarization, optical feedback, aging, and operating conditions.
Analyze SOA gain, gain saturation, wavelength-dependent gain, polarization-dependent gain, ASE noise, carrier dynamics, thermal behavior, and nonlinear effects.
Build, validate, and maintain automated optical and RF measurement setups using Python, PyVISA, LabVIEW, MATLAB, or similar tools.
Use modeling and design-analysis software to support characterization planning and data interpretation, including tools for laser physics, optical gain, rate-equation analysis, thermal modeling, optical spectrum analysis, and system-level performance estimation.
Develop scripts and software workflows for instrument control, automated data collection, calibration, data processing, visualization, statistical analysis, and automated reporting.
Debug complex optical, electrical, RF, and thermal measurement issues, including optical coupling, polarization sensitivity, back-reflection, RF noise, grounding, calibration error, thermal drift, and instrument limitations.
Define measurement best practices, calibration procedures, data quality checks, and test documentation standards.
Translate characterization results into actionable feedback for laser design, photonics integration, packaging, system architecture, and reliability teams.
Support device bring-up from early engineering samples through mature validation and production-readiness phases.
Mentor junior engineers and help establish high-quality characterization practices across the team.
Prepare clear technical reports, design reviews, data summaries, and recommendations for cross-functional engineering teams.
