Designing a low-loss adiabatic taper from 500 nm Si waveguide to 3 µm SiN routing layer.

Optiwave Systems Inc. is a specialized provider of software. Unlike general-purpose electromagnetic solvers (e.g., Lumerical, COMSOL), Optiwave focuses on bridging the gap between physical layer physics and system-level communication performance. Its flagship products— OptiSystem , OptiBPM , and OptiSPICE —are widely used in academia and industry for designing fiber-optic links, silicon photonic modulators, and integrated PICs. optiwave

| Feature | Optiwave (OptiSystem) | Lumerical (INTERCONNECT) | VPIphotonics | |--------|----------------------|--------------------------|---------------| | | Excellent for multi-span, amplified, coherent links | Good for PICs + lasers, less mature fiber model | Very strong for submarine & long-haul | | PIC layout & FDTD | Weak (no built-in FDTD) | Best-in-class (FDTD, EME, varFDTD) | Moderate | | Electronic-photonic co-sim | OptiSPICE (native) | Through Cadence/Keysight integration | Limited | | Learning curve | Gentle (GUI-first, block diagrams) | Steep (scripting in Lua/Python) | Moderate | | Cost (academic) | ~$5k–$10k per tool | ~$15k–$30k per tool | ~$20k+ | Designing a low-loss adiabatic taper from 500 nm

Optiwave’s competitive niche is and communication systems engineering . Where Lumerical dominates nanometer-scale FDTD for photonic crystals, Optiwave dominates the “how many km can this signal travel before the BER exceeds 2e-4?” question. Unlike general-purpose electromagnetic solvers (e
