VPIphotonics announces VPIphotonics Design Suite – Version 11.3 for photonic components and optical transmission systems
Design software specialists VPIphotonics has released VPIphotonics Design Suite Version 11.3. This latest version of the company’s design software suite continues to comprise access to application-specific simulation tools and pluggable toolkits. Version 11.3 offers enhancements designed to aid such applications as data-aided digital signal processing, forward error correction, free-space optical communications, Raman pump optimization, grating couplers, semiconductor optical amplifiers (SOAs), and multimode coupling, among others.
Key features of VPIphotonics Design Suite Version 11.3. include:
- Improved sorting of DSP algorithms with updated categories
- New modules add/remove arbitrary sequences of pilot symbols for pilot-aided DSP algorithms
- New algorithms for frequency offset compensation and maximum likelihood based carrier phase recovery that exploit pilot symbols for single- and multicarrier signals
- Enhanced FEC encoder/decoder to support Reed-Solomon codes of user-definable codeword lengths
- Direct calculation and display of signal metrics for PAM4 signals in the Analyzer
- FSO channel that includes an enhanced model to simulate Gaussian beam propagation through a turbulent atmospheric channel in a satellite uplink and downlink
- New M-ary pulse position modulator with any number of bits per symbol using Gaussian-shaped pulses and corresponding demodulator
- Enhanced Raman pump optimizer module to support multiple optimization wavelength ranges and pumps within them
- A new module that interfaces to Zemax OpticStudio to calculate the light coupling between two multimode waveguides via an optical imaging system
- Extended PIC Elements modules to support passive device modeling with absent or wrapped phase information in device S-Matrix files
- A new passive grating coupler with a measured and behavioral model supporting various spectral transfer functions
- Measured SOA with length-independent model definition and support of a chain of subsections to accurately calculate device properties
- New dialog to overview parameter usage, search for a parameter, or change parameter values in multiple schematics at once
- Enhanced support to copy signals between different Analyzer frames and Analyzer windows using different axis units
- A new approach to debugging Python co-simulation, simulation scripts, or initialization scripts based on Microsoft Visual Studio Code
- Simplified update of obsolete module versions with redesigned Resource Replacement Wizard Version 11.3 provides access to more than 900 ready-to-run simulation setups.
