The readme states

There are a number of other features in the device model class, such as returning an image of the structure. These features are best explored by reading the code and the function docstrings, as we don't have comprehensive standalone documentation at this time.

I have been going through the code and was not able to identify functions used to plot the simulations/structures.
Maybe you can point me in the right direction?

Hello,

In the presentation, it is confirmed: "The code in this module was used to produce the results in the [Inverse Design of Photonic Devices with Strict Foundry Fabrication Constraints] paper."

The thing is taking in account for the example "waveguide bend" as its explained in "Usage" section, the objects overrides design parameters but Fabrication Constraint parameters are not inputs for simulations and I don't know how to make the inverse design of one of this results that's shown in the paper. If it is possible can you illustrate us with a full example for "waveguide bend" for example? (I remark if it is possible)

It is the loaded parameter for simulation, there are others for fabrication constrains, where are they?? the code is full to got results in the paper?

def waveguide_bend_2umx2um_spec(**overrides) -> spec.WaveguideBendSpec:
"""Design spec for a waveguide bend with a 2 um x 2 um design region."""
defaults = spec.WaveguideBendSpec(
wg_width=200 * u.nm,
wg_length=750 * u.nm,
wg_mode_padding=750 * u.nm,
padding=400 * u.nm,
port_pml_offset=50 * u.nm,
variable_region_size=(2000 * u.nm, 2000 * u.nm),
cladding_permittivity=1.0,
slab_permittivity=12.25,
input_monitor_offset=50 * u.nm,
pml_width=20,
)
return dataclasses.replace(defaults, **overrides)

def waveguide_bend_sim_params(**overrides) -> params.CevicheSimParams:
"""Simulation parameters appropriate for the waveguide bend."""
defaults = params.CevicheSimParams(
resolution=50 * u.nm,
wavelengths=u.Array([1550.], u.nm),
)
return dataclasses.replace(defaults, **overrides)

I'm waiting for replaying and thanks in advance,
