Why Choose RSoft Photonic Design Tools
Bring photonic innovations to market faster with integrated design and simulation solutions.
Increase productivity and reduce the cost of physical prototyping with RSoft photonic device tools. Keysight offers a comprehensive portfolio of simulators and optimizers for passive and active photonic and optoelectronic devices, including lasers and vertical-cavity surface-emitting lasers (VCSELs). The tools integrate with additional optical and semiconductor design tools to accelerate multi-domain co-simulations. For example, use the interoperability between Keysight optical design tools, specifically CODE V and LightTools for rigorous modeling of nano-textured optical structures and diffraction analysis.
Extend Device Modeling into PIC Design
RSoft Photonic Device Tools integrate with ADS Photonic Designer to connect physics-based device simulation with photonic integrated circuit (PIC) design. Engineers can optimize devices in RSoft, generate reusable models and custom PDK components, and use those results directly within ADS Photonic Designer for circuit simulation, layout development, and performance verification. This workflow helps maintain consistency between device and circuit design activities while reducing manual model transfer between tools.
