RSoft Products: What's New

The latest RSoft™ product releases streamline  photonic and optoelectronic modeling of silicon photonic and photonic integrated circuit devices and systems.

RSoft Photonic Component Design Suite Version 2017.09

New and enhanced features in the RSoft Photonic Component Design Suite version 2017.09 include:

  • S-Matrix/PDK Generation Utility to automate the interface between the RSoft component tools, the RSoft OptSim Circuit tool and mask layout tools. The utility creates the S-matrix of a photonic component using the RSoft FullWAVE, BeamPROP and ModePROP tools and exports it to OptSim Circuit to verify its performance in a photonic integrated circuit (PIC) or system. The final design can then be easily exported to mask layout tools to create an optical process design kit (PDK). The interface allows designers to efficiently create PICs from basic building elements and accurately test PIC performance prior to fabrication.

  • Expanded effective index method (EIM) implementation in RSoft component tools. EIM is a sophisticated method for reducing 3D waveguide structures, such as silicon photonics components, into equivalent 2D structures for extremely fast, accurate performance simulations. EIM can increase simulation speeds by 100x or more.
  • Improved RSoft FullWAVE pulsed and broadband simulation. This feature allows engineers to accurately simulate the spectral response of photonic devices over a wide wavelength, or spectral, range with just a single simulation. It is especially useful for analyzing resonant devices, such as ring resonators.
  • Expanded documentation and examples that demonstrate how the RSoft tools’ proprietary sub-cell meshing capabilities can significantly improve the accuracy and speed of photonic component simulations.

RSoft Photonic System Design Suite Version 2017.09

New features include:

  • Interface between the RSoft OptSim and OptSim Circuit tools and Synopsys’ HSPICE tool for seamless optoelectronic analysis. With over 25 years of successful design tapeouts, HSPICE is the industry's gold standard electrical circuit simulator and offers foundry-certified electrical MOS device models. The RSoft-HSPICE interface supports precise co-simulation of electronic components in photonic circuits in both on-chip and off-chip optical configurations. RSoft OptSim and OptSim Circuit are the only photonic simulation tools on the market that offer this capability.
  • Updated PDKs, including the American Institute for Manufacturing Integrated Photonics (AIM Photonics) PDK version 1.5b and imec PDK version ISIPP50G. The PDKs help save PIC design costs and bring designers a step closer to fabrication through facilities supporting the AIM and imec processes.

  • Support for PhoeniX Software’s OptoDesigner elastic connectors. Constraints from packaging and design rule checks can impose restrictive routing requirements on schematic-driven layouts. To help overcome these constraints, OptSim Circuit supports OptoDesigner elastic connectors, where the shape and dimensions of the connectors are determined through tight integration with layout generation, and equivalent compact models for these connectors are created and simulated in OptSim Circuit.
  • Addition of the Viterbi and Viterbi (V & V) Mth power Carrier Phase Estimation algorithm in the OptSim digital signal processing (DSP) library for MATLAB. Accurate estimation of the optical carrier in phase-modulated coherent fiber-optic transmission systems is a vital responsibility of DSP at the receiver. As the order of modulation increases, susceptibility to laser phase noise requires accurate methods for phase estimation. The V & V Mth power algorithm in OptSim helps designers achieve accurate estimation of carrier phase for QPSK and PM-QPSK modulation formats.
