Proficiency with commercial device simulation software used to support design decisions with production intent — including one or more of: traveling wave laser model tools (e.g., VPI Photonics, Lumerical INTERCONNECT, Photon Design HAROLD), waveguide and mode solvers (e.g., Ansys Lumerical MODE, Photon Design FIMMWAVE), grating/EME solvers, and band structure or gain simulation tools (e.g., Crosslight, SiLENSe, or equivalent); scripting in MATLAB or Python for simulation automation and data analysis. Design and optimize III-V heterostructures and multi-quantum well (MQW) active regions for laser, SOA, and electroabsorption modulator applications, with explicit consideration of growth tolerance, process variation, and production yield; develop and maintain active region simulation models using commercial tools (e.g., band structure solvers, 1-D optical confinement solvers, traveling wave laser models).
