We can help demonstrate value across the spectrum.

Component Design Suite

RSoft’s Photonics Component Design Suite

RSoft’s Photonic Component Design Suite allows users to design and simulate both passive and active photonic devices for optical communications, optoelectronics, and semiconductor manufacturing.

RSoft currently addresses both passive and active devices through two design suites: a Passive Device Suite and an Active Device Suite. Each suite includes a CAD environment, simulation engines, and an optimization utility.

Key Features
  • Highly accurate algorithms allow for rapid virtual prototyping reducing the need for costly and lengthy physical prototyping increasing productivity and decreasing time-to-market.
  • Assists in the discovery of new products by creating “what if” product scenarios.
  • Each algorithm engine shares a common CAD interface; the software can utilize multiple RSoft packages without having to import designs from one software to the next.
  • Scripting can be done with any programming language.
  • Includes automated parameter scanning via MOST.
  • Each simulation engine is licensed and sold separately, allowing users to choose only those that are relevant to their work.

Component Design – Passive Devices

RSoft CAD Environment™
RSoft CAD Environment™
The RSoft CAD Environment is the core program of the RSoft Passive Device Suite, and allows researchers and engineers to create systems for the design of waveguide devices, optical circuits, and other photonic devices. It acts as a control program for RSoft’s passive device modules, including BeamPROP, FullWAVE, BandSOLVE, GratingMOD, DiffractMOD, FemSIM, and ModePROP.

FullWAVE is a highly sophisticated simulation tool based on the Finite-Difference Time-Domain (FDTD) method for studying the propagation of light in a wide variety of photonic structures, including integrated and fiber-optic waveguide devices, as well as circuits and nanophotonic devices such as photonic crystals.

BeamPROP is the industry-leading design tool based on the Beam Propagation Method (BPM) for the design and simulation of integrated and fiber-optic waveguide devices and circuits.

DiffractMOD is a design and simulation tool for diffractive optical structures such as diffractive optical elements, subwavelength periodic structures, and photonic bandgap crystals.

BandSOLVE is the first commercially available design tool to automate and simplify the modeling and calculation of photonic band structures for all photonic crystal (PC) devices.

FemSIM is a generalized mode solver based on the Finite Element Method (FEM) that can calculate any number of transverse or cavity modes of an arbitrary structure on a non-uniform mesh.

GratingMOD is a general design tool for analyzing and synthesizing complicated grating profiles in optical fibers and integrated waveguide circuits for a wide variety of photonic applications.

ModePROP is an eigenmode expansion propagation tool that accounts for both forward and backward propagation and radiation modes.

Component Design – Active Devices

LaserMOD is a photonic device design software tool for simulating the optical, electronic, and thermal properties of semiconductor lasers and similar active devices.

Component Design – Options & Utilities

MOST, RSoft’s Multi-Variable Optimization and Scanning Tool, is an exciting solution to the critical problem of design optimization for photonic devicesvv

LED Utility™
The LED Utility accurately simulates novel LED structures and all materials involved. The utility simplifies common tasks associated with LED design and aids in the rigorous computation of extraction ratios and radiation patterns. It utilizes the RSoft CAD to describe the geometry and material properties and RSoft’s flagship simulation tool FullWAVE to model the LED.

Solar Cell Utility
The Solar Cell Utility provides an optical and electronic simulation solution for solar cell devices. The utility simplifies common tasks associated with solar cell design and aids in the rigorous computation of J-V curves, quantum efficiency spectra, and overall cell-efficiency.

Multi-Physics Utility
The Multi-Physics Utility 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.

Tapered Laser Utility™
Tapered Laser Utility
The Tapered Laser Utility provides an efficient and accurate design tool for analyzing and optimizing tapered semiconductor laser diodes.

System Simulation

System and Network

RSoft’s Optical Communication Design Suite allows users to design and simulate current and next generation optical communication systems at the signal propagation, network architecture, and packet level.

Currently three software packages are part of the suite:

  • OptSim, ModeSYS – Simulate single mode and multimode optical communication systems at the signal propagation level.
  • OptSim Circuit – Models single- and multi-stage bidirectional photonic integrated circuits (PICs)

These advanced tools enhance and accelerate user-modeling capabilities and provide real field design scenarios using extensive industry specifications. Our users include optical component and equipment manufacturers, system integrators, service providers, as well as government labs and academic institutions. Whether you are interested in maximizing performance, minimizing costs, reducing time to market, fast prototyping, or analyzing multiple “what-if” scenarios for optical communication systems, these tools will become an inseparable partner and the secret of your success.
