VPIphotonics Design Suite – Version 11.2

19 Jul 2021

New release of industry-leading design software for optical transmission systems and photonic components.

VPIphotonics Design Suite Version 11.2 provides access to professional application-specific simulation tools and pluggable toolkits. They offer common usability, design process and data analysis capabilities.

Version 11.2 delivers advances in simulation and design flow for many applications, such as encoding and digital signal processing for high-speed coherent systems, analysis of signal metrics for intensity modulated direct detection systems, free-space optical communications and multimode coupling, integrated photonics with nonlinear waveguides and microring modulators. Integration with a version control system allows to track changes of the design project in a collaborative environment.

Our software solutions have proven their benefits in winning and successfully performing many research and design projects. With the improved capabilities that are provided in Version 11.2, our design suite is set to deliver the same outstanding results in the future.

Short list of key features in Version 11.2

TDEC for NRZ — Transmitter and Dispersion Eye Closure for
NRZ signals; allows to vary sampling window positions and
photodiode type
• Analysis of PAM4
— PAM analysis with extended list of PAM4
metrics: signal-to-noise and distortion ratio (SNDR) and several
Jitter metrics included
• MLSE transitions
— Display of transition PDFs created by the
MLSE-based decision and BER estimation for NRZ and PAM4
• Probabilistic shaping (PS) with FEC — LDPC-IRA codes for
PS-mQAM with FEC; better performance and lower complexity
than regular LDPC codes
Short blocklength PS — Generation of multiple short shaping
blocks per FEC codeword for higher nonlinear tolerance of
encoded signals
• PS power scaling
— Optional output signal scaling to deliver
constant output PS encoded drive signals for any specified modulation
• Data-aided TDE-MIMO
— Data-aided TDE-MIMO DSP algorithm
for robust channel equalization for high-order modulation formats
and severe signal impairments (low SNR, large PMD)
• Electrical SSB QAM — Transmitter to generate an electrical
single side-band mQAM signal
• Digital Subcarrier Multiplexing
— Transmitters to generate
electrical and optical polarization-multiplexed mQAM signals
that employ DSCM
• FSO communications
— Model for Gaussian beam propagation
through terrestrial free-space optical channel; accounts for
atmospheric scintillation, beam divergence, and weather conditions
• Multimode couplers
— Support launch systems with different
media between input plane, optical elements’ planes, and output
• Measured SOA
— Semiconductor optical amplifier with arbitrary
nonlinear gain saturation
• Circuit-level MRM
— Bidirectional microring modulator; any
voltage dependence for effective mode index, attenuation, junction
• Dispersion slope in PIC modules
— Accurate description of
dispersive properties of photonic waveguides in much broader
wavelength range
• Nonlinear waveguide
— Bidirectional model of dispersive nonlinear
waveguides; accounts for dispersion, Kerr and two-photon
• Demo modules
— Library of specific or experimental modules
that were previously undocumented and hidden
• Matrix calculations in Python
— Perform simple math on rectangular
floating-point matrices, especially useful for coding,
DSP, data analysis
• Access to matrix data
— Send matrix data to the simulation
script or Simulation Engine Driver; for iterative control and optimization
• Multiple objects operations
— In one operation, activate multiple
instances on your schematic, or change the format of several
graphical objects
• Compact mode
— Convenient mode to extend the usable design
space for schematics that collapses or hides User Interface
• Version control
— Basic support of version control systems
(Mercurial, Git); allows to track changes of the design project in
a collaborative environment
