awg_designer.all.get_FSR(delay_length, n_g_c)

Get the actual FSR based on a delay_length and the group index at the center wavelength.

Parameters:
delay_length: float

The calculated delay_length.

n_g_c: float

The group index at the center wavelength.

Returns:
FSR [GHz]: the free spectral range (in GHz).
