NEW VERSION OptiSystem 11.0 (May 2012)

The latest version of OptiSystem features new enhancements to address co-simulation with the OptiSPICE software. Also a new simulation feature for parallel processing by using graphical processing unit (GPU) cards can be used to accelerate computations.

 

NEW FEATURE Parallel processing using graphical processing units (GPU). OptiSystem now supports the use of GPU cards to accelerate fiber link simulations. Please refer to the section on GPU Processing in the User Reference Guide.

The NVIDIA CUDA parallel computing architecture is enabled on GeForce®, Quadro®, and Tesla™ products. Whereas GeForce and Quadro are designed for consumer graphics and professional visualization respectively, the Tesla product family is designed ground-up for parallel computing and offers exclusive computing features, and is the recommended choice for the OptiSystem GPU. For the complete list of products, see the NVIDIA website at http://www.nvidia.com/page/products.html.

 

NEW FEATURE Optiwave Software Tools/OptiSPICE Netlist. A new component, OptiSPICE Netlist, was added to the Optiwave software tools library. The OptiSPICE Netlist component connects OptiSystem projects to optoelectronic circuits designed within OptiSPICE (by using netlist files).

 

NEW FEATURE OptiSystem/OptiSPICE Co-simulation. OptiSystem now supports the co-simulation of designs with the OptiSPICE optoelectronic circuit simulator. Time domain signals, defined as sampled signals in OptiSystem, are transferred between OptiSystem and OptiSPICE as electrical or optical signals. OptiSpice will receive the electrical signals as current or voltage depending on the input port defined at OptiSPICE ("Electrical Input - Isource" or "Electrical Input - Vsource" components), while optical sampled signals will be received in OptiSPICE by using the "Optical Input" component.

Within OptiSPICE the user sets up the OptiSystem Co-simulation component each with its respective Isource, Vsource or Optical input and proceeds to build the electric or opto-electronic circuit. Once complete, the OptiSystem/Configure Co-simulation task is selected to create the associated Netlist for the OptiSPICE circuit.

Within OptiSystem, the user then places the OptiSPICE Netlist component into the optical system design and seaches for the desired OptiSPICE circuit and uploads the associated Netlist file. Once configured, the ports for the OptSPICE Netlist component are automatically created to allow the user to integrate the OptiSPICE circuit into the OptiSystem design. When the project calculation starts, OptiSystem runs the simulation and transfer signals to OptiSPICE, then the Netlist circuit is simulated using the OptiSPICE simulator. After OptiSPICE completes its calculation, the signal is transfered back to OptiSystem to conclude the simulations.

Please refer to the “OptiSPICE Co-simulation” chapter in the OptiSystem Tutorials - Volume 2 for further details on how to setup and perform a co-simulation project with OptiSPICE and OptiSystem.

 

NEW FEATURE Optical Fibers Library/Multimode/Measured-Index Multimode Fiber. It is now possible to add material properties information to the Measured-Index Multimode Fiber component. The modal delay calculation now includes the material dispersion influence. Within the new Material Properties tab, the user can determine whether to include the material dispersion influence in the modal delay calculation. When selected, the user can define the host, dopant+ and dopant- material types, and link each material type to a Sellmeier coefficients text file.

 

NEW FEATURE MATLAB Library/MATLAB Component. The MATLAB component now supports the ability to run in a shared or dedicated mode. When in a shared mode, all connections to the server are shared through one instance of the Matlab server. When in a dedicated mode, each client connection is dedicated (separate instances).

 

NEW FEATURE Application and Validation Projects. Online access to OptiSystem project samples (www.optiwave.com/products/system_downloads.html) is available to all users of OptiSystem, including example projects for:
• All-Optical signal processing (Optical loop mirror, Wavelength converter, optical 2R/3R regeneration, Logic gates)
