Exports Hx, Hy, Hz, Ex, Ey, Ez for all the wavelengths and modes. Support to selected fields, wavelength and modes is pending.

Parameters:

filename (str, optional) – Export file name without extension. Defaults to ‘./field’.
field (str | list[str], optional) – Fields to be exported. Defaults to ‘all’.
