Photonic Solutions Enewsletter

We are pleased to announce the availability of the RSoft™ Photonic Component Design Suite version 2017.03, which provides the following updates.

• Sentaurus TCAD interface usability improvements, including support for dispersive materials and dynamic updating of materials and simulation domain. The RSoft/TCAD Interface enables unified simulation of advanced opto-electronic devices.
  
• Support for general monitor objects in BeamPROP™. This allows broader use of BeamPROP with the Sentaurus TCAD interface for applications such as waveguide photodetectors.
  
• Improved BSDF scattering calculation, including more accurate handling of polarization when input data is limited.
  
• Enhanced RSoft CAD Environment hierarchy features, including the ability to publicize design variables and allow a wider range of variables such as material choice. This enhances the ability to generate reusable sub-circuits and is utilized in the unit cell library for the dynamic array feature.
  
• Updated remaining 32-bit utilities, including MOST™, to 64 bit.

Please refer to the RSoft Photonic Component Design Suite 2017.03 Release Notes, available on our Customer Support Portal, for more details about these and other updates included in the release.

We are pleased to announce the availability of the RSoft Photonic System Design Suite (System Tools) version 2017.03, which provides the following updates.

In OptSim™:

• New DMT modulation functions for OptSim DSP Library. Discrete multi-tone (DMT) is an attractive alternative modulation format that uses intensity of light for modulation (and hence simpler receivers compared to coherent receivers) over multiple subcarriers (yielding higher spectral efficiency). For short-reach applications such as automotive links, access networks and 100G, 400G Ethernet based data center links, DMT has attracted a lot of attention. The digital signal processing (DSP) library of OptSim version 2017.03 now includes DSP functionalities to help model DMT-based data links.

In OptSim™ Circuit:

• Support for AIM Photonics PDK 1.0 and new PDAFlow libraries. The American Institute for Manufacturing Integrated Photonics (AIM Photonics) released their integrated silicon photonics PDK version 1.0. This PDK will help users access leading-edge silicon photonics technology to generate their own PIC for fabrication within the SUNY Poly silicon photonics process. OptSim Circuit users will be able to access these PDK elements, use them in OptSim Circuit schematics, and simulate circuit performance prior to exporting netlists for mask generation.
  
  
• New and updated libraries from the PDAFlow foundation for enhanced PDK support.

In ModeSYS™:

• Support for large-core fiber power-vs-angle signal domain across select models. Extends large-core multimode fiber’s numerically efficient power vs. angle approach for signal propagation to other models in ModeSYS to model a complete data transmission link. These links are of great interest to automotive link designers and to the providers of backplane Ethernet connectivity in modern mega data centers.
  
  
• Large-core connector model that is computationally more efficient compared to the conventional spatial field-profile based connector models. Users of large-core fibers such as automotive link designers and providers of backplane Ethernet connectivity in data centers will find this model helpful for their modeling needs.

In OptSim, OptSim Circuit and ModeSYS:

• OptSim Block-Mode, ModeSYS and OptSim Circuit now allow specifying key simulation parameters as global settings for the current design instead of having to adjust them in individual models. This is especially helpful in cases when signals of different types (such as optical signals and electrical signals) and/or with different data rates need to be combined either for modulation or for multiplexing. This feature is expected to improve the user experience and add to the convenience of those who use block-mode simulation in OptSim, OptSim Circuit and ModeSYS.
