Optiwave software can be used in different industries and applications, including Fiber Optic Communication, Sensing, Pharma/Bio, Military & Satcom, Test & Measurement, Fundamental Research, Solar Panels, Components / Devices, etc..
OptiSystem is a comprehensive software design suite that enables users to plan, test, and simulate optical links in the transmission layer of modern optical networks.
OptiSPICE is the first circuit design software for analysis of integrated circuits including interactions of optical and electronic components. It allows for the design and simulation of opto-electronic circuits at the transistor level, from laser drivers to transimpedance amplifiers, optical interconnects and electronic equalizers.
OptiFDTD is a powerful, highly integrated, and user friendly CAD environment that enables the design and simulation of advanced passive and non-linear photonic components.
OptiBPM is a comprehensive CAD environment used for the design of complex optical waveguides. Perform guiding, coupling, switching, splitting, multiplexing, and demultiplexing of optical signals in photonic devices.
The optimal design of a given optical communication system depends directly on the choice of fiber parameters. OptiFiber uses numerical mode solvers and other models specialized to fibers for calculating dispersion, losses, birefringence, and PMD.
Emerging as a de facto standard over the last decade, OptiGrating has delivered powerful and user friendly design software for modeling integrated and fiber optic devices that incorporate optical gratings.

When using the mode solver associated with OptiFDTD, there are ADI and FD Anlso methods. Can anyone suggest when to use ADI and when to use FD Anlso? My situation is that the waveguide is quite small (width: 450 nm x height: 220 nm). The input light wavelength is 1550 nm. There is always no mode found when using ADI method. When I use FD Anlso method, I found that there is one mode by setting the Eigenvalue Solver to Subspace Iteration. However, I am just doing try and error and not sure whether the mode is correct or wrong. Can anyone suggest what are those properties? Thanks!
The FD mode solver and ADI one use different meshes. Are they set the same in your project? The ADI mode solver sometimes misses modes if the complex acceleration parameter is not a suitable value. Can you attach the project that got these results? I might help us to find the reason for the difference.
Thanks Steve! After I reduced the mesh size, the ADI mode solver returned one mode. However, the mode is a bit different from the mode found by the FD method.
Modes Modal Index Polarization
Mode 1 2.31022444, -0.00336495 FVect TE (by ADI method)
Mode 1 2.34768099, 0.0 FVect TE (by FD method)
The FD more accurate for the small geometries less than 2 micrometre, due to concentrating of the mesh in a small scale that’s why the results become more accurate. for your case I suggest to used the FD mode.
Make sure that you are using the PML to obtain the accurate values.
