A degree in Physics or Electronic Engineering is required.
Proven hands-on experience in VCSEL or semiconductor laser design and simulation is required.
Proven FDTD simulation experience, such as Ansys Lumerical FDTD or a similar tool, is required.
A strong grounding in semiconductor laser physics, including optical cavities, gain, and carrier dynamics, is required.
The candidate must understand the theory behind the simulations, not only the tools.
A track record of validating models against experimental data is required.
The candidate must be able to communicate technical results clearly.
Responsibilities
Own the design and simulation of vertical-cavity surface-emitting lasers for next-generation optical links, using FDTD as the primary tool.
Model VCSEL optical, electrical, and thermal behavior from epitaxial structure to packaged device.
Use simulation results to shape epitaxial design, device layout, and process choices.
Help drive research into high-speed, energy-efficient light sources for optical interconnects.
Build VCSEL models covering DBR mirrors, the active region, oxide aperture, and optical cavity.
Run FDTD simulations of optical modes, cavity resonance, wavelength, far-field, and beam profile.
Model current spreading, self-heating, and thermal rollover using COMSOL or equivalent tools.
Simulate high-speed modulation and small-signal response for optical interconnect links.
Run parametric studies to guide epitaxial design, aperture size, mirror design, and device layout.
Validate models against measured LIV, spectral, and high-speed data, and turn results into clear design rules.
Desired Qualifications
A PhD or MSc is an advantage.
Wider simulation tools such as Crosslight PICS3D, RSoft, or COMSOL are a plus.
Join our photonics team and work at the forefront of microLED and optical interconnect technology. As our Senior Photonics Simulation Engineer you will own the design and simulation of vertical-cavity surface-emitting lasers for next-generation optical links, using FDTD as the primary tool.
You will model VCSEL optical, electrical and thermal behaviour, from epitaxial structure to packaged device. Your results will directly shape epi design, device layout and process choices. You will also help drive new research into high-speed, energy-efficient light sources that push what optical interconnect can do.
