VPIphotonics upgrades its VPIdeviceDesigner tool
The company says that the product’s new functionalities can help to streamline material definition, 3D design workflows, and light propagation simulations
VPIphotonics has announced the release of VPIdeviceDesigner version 2.7, a simulation framework designed for analysing and optimising optical devices, waveguides, and fibres, with an emphasis on integrated photonics applications. The company says its design tool offers 2D and 3D full-vectorial finite-difference beam propagation and eigenmode expansion solvers for modelling optical devices and a set of semi- and full-vectorial finite-difference mode solvers for modelling straight and bent waveguides and fibres made of iso- and anisotropic (including plasmonic and gyrotropic) materials.
According to VPIphotonics, VPIdeviceDesigner offers new functionalities, including: new permittivity models to support amorphous semiconductor materials; an upgraded 3D geometry kernel to enable the creation of complex 3D structures like photonic lanterns and tapered fibre couplers; and automatic simulation settings in the EME solver for faster convergence, particularly in tapered regions, and offers increased user control for advanced needs.
The company adds that version 2.7 significantly extends the product capabilities in modelling photonic devices, simulating photonic waveguides and optical fibres, and introduces four new application examples: anisotropic dispersive lithium niobate waveguide; effective index model for MQW-like layer stacks; efficient mode calculation in MQW waveguides; and photonic lantern with BPM.
