VCSEL & Semiconductor Device Simulation
See How Your VCSEL, or Any Semiconductor Device, Performs Before You Build It
Po.Li.Te’s software predicts how a semiconductor device will perform (electrical behavior, heat, optical response) on a laptop, before a single wafer is fabricated. It stands on two equally solid foundations: a fully coupled VCSEL workflow, the tiny laser chips behind face-recognition cameras, LiDAR and high-speed data links, backed by nine peer-reviewed publications; and a drift-diffusion transport solver coupled to thermal analysis, which applies to any semiconductor device family, from photodetectors to power and cryogenic CMOS. R&D teams use it to catch a bad design in simulation instead of in the fab.

What We Do
Po.Li.Te is purpose-built software for VCSELs and for semiconductor devices more broadly, predicting exactly how a design will perform before it ever reaches a cleanroom.
Unlike general-purpose TCAD tools, our platform is built from the ground up for device-specific physics, enabling
Multiphysics Device Optimization
Full-vector 3D optical, thermal and transport solvers, tightly coupled together, that handle the complex, non-cylindrical geometries other tools can’t.
Performance
Every simulation runs on a standard laptop — no HPC cluster required.
Full 3D, Not an Approximation
A complete 3D full-wave solution, fast enough to run in minutes — nothing about the real device geometry gets simplified away.
The Problem We Solve
Developing a new VCSEL, or any new semiconductor device, typically requires:
- Multiple wafer iterations
- Long fabrication cycles
- Fragmented simulation workflows
- Heavy reliance on empirical fitting
Existing tools are either too generic, computationally inefficient, or limited to simplified geometries.
Po.Li.Te replaces all of that with one unified, predictive design framework — from first concept to a design ready for the fab.
Where Po.Li.Te Applies
VCSELs are where our physics is most complete, and the same coupled transport and thermal core carries that accuracy into other device families:
- Semiconductor lasers and VCSELs: flagship workflow, fully coupled, validated
- Photodetectors and optical sensors: validated
- Power semiconductor devices (CMOS, diodes, HEMT): validated
- Integrated photonics and active optoelectronics: emerging
- Quantum and cryogenic semiconductor devices: emerging
Design for new generation and innovation
A fast, fully 3D vectorial solver cuts the cost of developing next-generation semiconductor and optoelectronic devices.
Use Po.Li.Te however suits you best: through the GUI, by importing your own structure files, or via Python scripting.
Saving prototyping time
Physical and predictive solution to semiconductor device design
Reduction of costs
A TCAD-style approach cuts R&D costs on average, resulting in cheaper, faster next-generation designs.
More accurate
A full 3D vectorial solver captures every aspect of the device, not just an approximation of it.
Grounded in Peer-Reviewed Research
Po.Li.Te’s simulation engine is built directly on the team’s own published research in VCSEL physics, not adapted from general-purpose tools. Our work has been peer-reviewed by leading photonics journals and presented at IEEE conferences.
