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 2018.03

New and enhanced features in the RSoft Photonic Component Design Suite version 2018.03 include:

  • Major enhancements to the S-Matrix/PDK Generation Utility, which automates the creation of custom process design kit (PDK) models to create a new PDK, augment an existing PDK, or generate IP. The PDK models can also be simulated in Synopsys' OptSim™ Circuit and exported to a circuit layout tool such as PhoeniX OptoDesigner. 
  • Enhanced support for all silicon photonics applications, including:
  • New 3D wide-angle BPM algorithms, further extending BeamPROP's capabilities to simulate structures in silicon or other high-index contrast materials
  • Improvements to FullWAVE modeling of dispersive materials, including automatic optimized fitting of materials and an approximately 30% speed improvement in the FDTD algorithm. 

RSoft Photonic System Design Suite Version 2018.03

New and enhanced features in the RSoft Photonic System Design Suite version 2018.03 include:

  • In OptSim, support for m-QAM and arbitrary constellation shaping in OptSim DSP Library for MATLAB
  • In OptSim Circuit:
    • American Institute for Manufacturing Integrated Photonics (AIM Photonics) APSUNY PDK v2.0b
    • Support for parametric custom PDK components created with the RSoft component tools S-Matrix/PDK Generation Utility
    • Support for hierarchical components in the interface between RSoft OptSim Circuit and PhoeniX OptoDesigner tools
    • Bidirectional NxM Electrical S-matrix block supporting Touchstone file format 

A 4-channel filter created in OptSim Circuit using foundry PDK components including input coupling, splitters, and photo-detection combined with a parametric custom PDK element produced by the RSoft tools.

The custom PDK component was produced using this simple coupler shown here in the RSoft CAD. The delay line length shown was varied to produce the parametric PDK model. The delay length sets the resonant wavelength for a particular channel and the number of couplers used in the channel sets the filter bandwidth.

S-Matrix data calculated using FullWAVE at a particular delay line length.

Spectral response calculated by OptSim Circuit.
