Synopsys Inc. has unveiled the version 2015.06 of the RSoft product line-up. The RSoft Photonic Component Design Suite claims to deliver advanced finite-difference time-domain (FDTD) simulation features as well as significant speed and usability improvements. The RSoft Photonic System Design Suite includes additional libraries of components and algorithms to streamline the design of photonic chips, modulator circuits and coherent transceivers, as well as an innovative platform for modeling large-core multimode fibres, noted the company.

The enhancements in version 2015.06 promise to facilitate faster, more efficient design of a range of current and emerging photonic devices, photonic circuits and fibre-based applications.

The RSoft Photonic Component Design Suite features FullWAVE FDTD simulations that now contain both anisotropic and dispersive materials. This provides designers with highly accurate simulations of photonic structures that contain metals and other materials with complex dispersion characteristics such as twisted nematic crystals used in LCDs, surface plasmonics and metamaterials. It also offers additional FullWAVE options to arbitrarily rotate and vary the crystal axes of anisotropic materials simplify the simulation of LCDs containing multiple anisotropic layers at different orientations.

The design suite also boasts increased efficiency of FullWAVE simulations when used on multi-CPU computers yields speed increases of up to 3X. The Arrayed Waveguide Grating (AWG) Utility has been updated with ease-of-use improvements, greater flexibility, and support for silicon-based AWGs. In addition, an updated Bidirectional Scattering Distribution Function (BSDF) capabilities include a graphical user interface for the calculation of BSDF files and improved handling of dispersion by the RSoft BSDF User Defined Optical Property (UDOP) interface for use with Synopsys' LightTools illumination design software.

RSoft BSDF capabilities provide a highly accurate method for modeling an optical surface's scattering properties and help designers achieve stringent size, weight and cost targets. New features in The RSoft CAD Environment help make design creation and management faster and easier, especially when working with multiple design files, added the company.

The RSoft Photonic System Design Suite features the OptSim Circuit tool where IMEC foundry process design kits (PDKs) help photonic chip designers incorporate foundry-specific components into their circuit designs, bringing them closer to the foundry process ecosystem. In addition, traveling wave Mach-Zehnder modulator circuit components provide designers with an insight into complex bidirectional optical and RF signal interactions.

In the OptSim tool, a MATLAB library of digital signal processing (DSP) algorithms for coherent transceivers gives designers flexibility to pick and choose from the supplied library of DSP algorithms, make changes, or incorporate their own algorithms and evaluate system performance. In the ModeSYS tool, modeling of large-core step-index multimode fibres based on the Gloge power-flow approach provides a more efficient approach to modeling large-core (200?m and larger) multimode fibres and analysing encircled angular flux (EAF).

Synopsys' RSoft products version 2015.06 are available.
