Dear all,
 I am happy to join GDS factor group. I wish to make gds for an elliptical grating coupler. For that, i have to vary the pitch and tapering length. But in the default component design, these two functions are there separately.  Please help me to make vary both parameters in a single file.

Hi Nagarajan,

maybe you find the grating_coupler_elliptical_arbitrary useful


otherwise you can use that Pcell as inspiration to write your own

Dear Joaquin,
 I tried the grating coupler elliptical arbitrarily. After running in python it shows error

ValidationError: 1 validation error for CrossSection
kwargs
  unexpected keyword argument: 'taper_to_slab_offset' (type=type_error)

Hi Nagarajan,

You can see an example on how to run each component here
