What's New in Photonic Solutions

RSoft Photonic Device Tools

The RSoft Photonic Device Tools comprise the industry's widest portfolio of simulators for passive and active devices in optical communications and optoelectronics. New features in version 2019.09 include:

  • The RSoft - LightTools Bidirectional Scattering Distribution Function (BSDF) interface for multi-domain device simulation now supports faster ray tracing of user-defined optical properties; it also supports non-uniform incident angles for more efficient use of computer resources in critical angular regions.
  • A new interface with OptoDesigner allows users to load and simulate PIC design files directly in the RSoft CAD Environment.
  • New Python APIs help construct CAD files for complex structures, such as metalenses and grating couplers.
  • An expanded Custom PDK Utility allows users to add to a PDK active device models such as phase shifters and modulators; it also enables users to design and create layouts for custom circuits such as ring modulators in OptSim Circuit and OptoDesigner.

Photonic System Tools

The OptSim and ModeSYS tools simulate the performance of optical communication system links through comprehensive simulation techniques and component models. New features in release 2019.09 include:

  • The ability to simulate design files in multiple OptSim windows simultaneously, as well as to pre-assign signal types to compound component input and output ports.
  • New application notes and design files to jumpstart designs for BPSK modulation, visible light communication, and 100GBASE-SR4 SWDM4 transmission.

PIC Design Suite

New features in version 2019.09 of our PIC Design Suite, which includes the OptSim Circuit and OptoDesigner tools, are:

  • Enhanced algorithms for inter-domain conversions (time and frequency) in OptSim Circuit that speed simulation times by up to 2x.
  • New design rule checks (DRCs) in OptoDesigner that speed calculations by up to 20x.
  • Significant improvements to the PIC layout versus schematic (LVS) flow to support large port count photonic devices and netlist extraction.
  • Updates to the bidirectional interface between OptSim Circuit and OptoDesigner to support automated electrical connections in layout.
