Extracting S-parameters from complex photonic integrated circuits (PICs).
) is a technical hub where engineers and researchers troubleshoot complex electromagnetic simulations. Discussions typically center on fine-tuning solvers like
User: I'm simulating a 1D grating (period 500 nm, duty cycle 0.5, thickness 100 nm, Si on SiO₂). Plane wave source at normal incidence, wavelength range 400–800 nm. Transmission monitor placed after the structure. lumerical forum
Connecting Lumerical with OpticStudio for photonics-lens integration.
Today, the official home of the "Lumerical forum" is the . This is the primary destination for users to ask technical questions, share knowledge, and report issues.
: Support registration is not required to browse the ALF, making it more accessible for prospective users and students. Are you currently stuck on a or looking
The forum had rules, of course: citation when borrowing code, patience with newcomers, and a distaste for point-scoring. Reputation meant something, but more powerful was the implicit contract among users: help when you can, document what you learn, and leave things a bit better than you found them.
If possible, upload a simplified version of your .fsp (FDTD) or .lms (MODE) file. Remove proprietary geometry, but keep the core setup that reproduces the bug. Experts are much more likely to download and fix a file than to guess the issue from a text description. Python and Interoperability Discussions
I see a sharp dip at ~650 nm that I don't expect from theory (should be a smooth response). Mesh refinement is set to 'conformal variant 1', and I've tried both 'staircase' and 'conformal' meshing. and an Example Script/Code Share .
Students and researchers with academic licenses should use the ALF for all their technical inquiries. The forum is designed as the primary support channel for academic users.
I have provided three common archetypes: a , a Reply/Solution , and an Example Script/Code Share .
