Over 130 demonstrations of VPIcomponentMaker Photonic Circuits capabilities

Accurate analytical models for standard passive photonic devices: straight and bent waveguides, reflective waveguide junction and crossing, Y-branch, X-coupler, MMI, star coupler, ring resonator and ring coupler, waveguide Bragg grating that supports arbitrary user-defined apodization and chirp as well as sampled and nonreciprocal grating profiles
Arbitrary frequency-dependent effective mode indices and attenuations can be specified independently for TE- and TM-like modes in all analytical device models
Fast and memory-efficient implementation of the cascaded scattering matrix (S-matrix) approach for frequency-domain modeling of passive photonic circuits that consist of any built-in, measured, cosimulated or compound passive devices. This enables modeling photonic integrated circuits with thousands of components

Fast automatic on-the-fly design of accurate FIR filters for time domain modeling of individual devices as well as any passive subcircuits
Loading/saving S-matrices for individual devices as well as for any passive subcircuits. This feature allows, in particular, to accurately model real measured devices
Python cosimulation for easy adding passive photonic devices with arbitrary user-defined S-matrices. This also allows to create on-the-fly integration with external mode solvers and wave propagators or to add foundry design kits
