I have designed an optical device using the variational FDTD in Lumerical MODE or in Lumerical FDTD. (For example, a ring resonator or MMI). Now, I have the geometry, have the device simulated in Lumerical, and I have a .lms or .fsp file for it. I would like to fabricate this device, so I need to create a layout (.gds) file in Cadence.
I don’t want to redraw the structure in Cadence (it could be difficult for some of the structures I have scripted in Lumerical). Is there a way (software, Lumerical file, python code, etc.) by which I can directly convert a geometry in Lumerical to a Cadence layout (.gds file)? For now, my Lumerical designs are just single-layer passive devices.
