Multi-Physics Utility Product Overview
Integrated Simulation Software for Modulators, Switches, Waveguides, Fibers
The Multi-Physics Utility™[1] is designed to be used in conjunction with any of RSoft's passive device simulation tools. It provides a convenient interface from which perturbations of the refractive index profile of a structure may be included in the simulation. These perturbations can be caused by advanced physical processes in the material, such as electro-optic effects, thermo-optic effects, stress-optic effects (i.e., strain), and carrier-induced effects. All material parameters needed to describe these effects can be defined in RSoft's Material Library.
[1] The basic Multi-Physics Utility with electro-optic and thermo-optic effects is included with all passive device tools; the stress and carrier effects are offered as options that are licensed separately.

Benefits
- Expands the power of all of RSoft's passive device simulation tools.
- Fully integrated into the RSoft CAD Environment.
Applications
- Electro-absorptive/electro-refractive modulators
- Thermo-optic switches
- Electrically biased modulators
- Birefringence in waveguides and fibers
- Stress effects caused by cooling during device fabrication
Features
- Fully integrated with all of RSoft's passive device simulation tools.
- Leverages RSoft's material library for all model parameters.
- Computes index perturbation by solving Poisson's equation (electro-optic effect), thermal equation (thermo-optic effect), stress-strain equation (stress effect), and by using LaserMOD to model carrier-based effects.
- Automated parametric studies and design optimization using MOST
