What's New in Photonic Solutions

Photonic Solutions 2021.09-2 Releases Now Available

We are pleased to announce the availability of version 2021.09-2 of the RSoft Photonic Device Tools, OptSim and our Photonic IC Solutions. New features and improvements include:


OptoCompiler 2021.09-2 Release Highlights:

  • Miscellaneous bug fixes and improvements

OptSim 2021.09-2 Release Highlights:

  • Enhancements to E-O co-simulation
    • The framework of E-O cosimulation was enhanced to support photonic models of an iPDK from a major foundry that added bidirectional signal flow to their iPDK
  • New GaussianVsWavelength filter type in Optical Filter model
    • The Optical Filter model of OptSim represented a variety of analytic and user-defined optical filters. A new GaussianVsWavelength filter type was added to the model. It uses a Gaussian filter response as a function of wavelength to filter the optical signal amplitude.  The user specifies the 3dB bandwidth and the order of the filter. 
  • Miscellaneous bug fixes and improvements

Photonic Device Compiler 2021.09-2 Release Highlights:

  • Improvements to the Custom PDK Utility Alchemy Design Flow
  • Miscellaneous bug fixes and improvements

Version 2021.09-1 Service Release

On November 9, we released version 2021.09-1 of OptoCompiler, OptSim and Photonic Device Compiler. Updates include:

  • E/O co-simulation is now more integrated than ever
  • OptoDesigner script files can now be encrypted
  • Engineering notation support added to tcls helper function
  • A new thermal phase shifter model that allows analytic and data file-based modeling of thermal phase shift in PICs
  • New gain and amplified spontaneous emission (ASE) data file-based behavioral model of a semiconductor optical amplifier (SOA)
  • New behavioral model of lasers based on measured power vs. current (L-I) curve
  • Improved models for waveguides and phase shifters that account for parametric variations in effective index files as a function of device geometry
  • Improved photodetector model now has an additional frequency response option
  • Miscellaneous bug fixes

Photonic Solutions 2021.09 Release

We are pleased to announce the availability of version 2021.09 of the RSoft Photonic Device Tools, OptSim and our Photonic IC Solutions. New features and improvements include:

RSoft Photonic Device Tools:

  • New far-field calculation in inhomogeneous regions, enabling faster and more accurate calculations for total-scattered field calculations and LED extraction and radiation pattern calculations
  • Native support for LSF Batch Schedulers for FullWAVE FDTD and MOST clustered simulations that simplifies the use of high-performance computing systems
  • The RSoft Advanced BSDF UDOP now includes optical phase, enabling use with coherent ray tracing and compensating for the optical path length (OPL) in the Synopsys  LightTools ray tracing simulator
  • Increased number of concurrent processes per license seat to 32, enabling customers to simulate larger problems and more fully utilize computers with many CPU cores. This change applies to FullWAVE FDTD, BeamPROP BPM, ModePROP EME, DiffractMOD RCWA, and FemSIM FEM. Note that this change was first included in v2021.03-3
  • Miscellaneous bug fixes and improvements


  • Flexible bus waveguides, including:
    • Interactive waveguide routing of a whole bus of waveguides
    • Automatic fan-in and fan-out
    • Optional enforcement of length differences among the waveguides in the bus
  • More flexibility for single flex connectors
  • Miscellaneous bug fixes and improvements


  • Support for Linear Time Invariant simulation speed-up with OptoCompiler
  • Monte Carlo simulation enablement with PrimeWave
  • Ease of use and speed improvements for electro-optical co-simulation
  • Miscellaneous bug fixes and improvements

Photonic Device Compiler:

  • Additional Custom PDK Utility workflow to simplify automatic cell creation for OptoCompiler and OptSim symbol, model, layout and LVS views


  • New bus framework with automatic length adjustments allows designers to easily route many waveguides with prescribed length differences around the chip, without the need for cumbersome manual adjustments
  • Script function override control to ensure that a function or layout definition is not accidentally overwritten, avoiding errors
  • Miscellaneous bug fixes and improvements
