Version 9.5 provides new modeling features, improved usability and advances in design process and data analysis compared to the previous versions.
Among the new features are multimode fiber modeling accounting for Kerr nonlinearity, improved analysis and visualization of multimode signals, parameter library of typical multimode fibers, accurate modeling of micro-rings and Fabry-Perot resonances in multi-section optoelectronic devices, a new discretization approach to dramatically speed up calculation of active sections in optoelectronic devices, ENoB calculation in ADC, additional and enhanced DSP algorithms for coherent transmission systems and many more.
The graphical user interface has been enhanced to improve the handling of and navigation through resources and simulation schematics. The capabilities of parameter and user interface scripting using Python have been significantly increased.
Version 9.5 is compatible with version 2.0 of the VPItoolkit DSP Library – a pluggable toolkit to VPItransmissionMaker Optical Systems and VPIlabExpert – providing new functionality such as data-aided frequency domain equalization using for example CAZAC sequences, and means for off-line processing of experimental data.
Detailed multimode fiber modeling considering not only linear dispersive effects, but also self-phase and inter-/intramodal cross-phase modulation caused by the Kerr nonlinearity
New macro to apply directly typical parameter values of OM1, OM2, OM3, or OM4 fibers according to ISO/IEC 11801
Support of binary Zemax® beam files (.zbf) to describe an optical beam and calculate the coupling coefficients between this beam and a multimode fiber or waveguide
Accurate account for the spectral dependence of the fiber index profile by the fiber mode solver, which can significantly improve Differential Group Delay calculations
Enhanced multimode system-level amplifier model to support the individual definition of wavelength-dependent gain and noise characteristics for different spatial modes
Significantly enhanced support of multimode signal analysis functions in the VPIphotonicsAnalyzer
Existing demonstrations have been modified and new ones added to illustrate the functionality and applications of the new features and modules. There are over 770 demonstrations available in the products now.
