Inverse-design dataset for the EngiBench photonics2d problem: 2D photonic wavelength
demultiplexers optimized with a finite-difference frequency-domain (FDFD) solver (ceviche).
Each design routes light at two wavelengths to two separate output ports.
v1 makes simulate and optimize mutually consistent: designs are stored as physical (projected)
densities in [0, 1], and simulate evaluates them as-is, so the… See the full description on the dataset page:
