<p>Hello Minu,<\/p><p>I wouldn’t suggest to change the script because in this case you would need to create a new workflow if you want to avoid the polynomial fit.<\/p><p>Since you have the data for both modes you can interpolate them.<\/p><p>If for example you have the following data for mode 1 (assuming in the brackets you have the values from the table you shared):<\/p><p>wavelength_mode1 = [… , … , … , … , … , …]<\/p><p>neff_mode1 = [… , … , … , … , … , …]<\/p><p>and for mode 2:<\/p><p>wavelength_mode2 = [… , … , … , … , … , …]<\/p><p>neff_mode2 = [… , … , … , … , … , …]<\/p><p>you can write the following commands:<\/p><p>neff_mode2_new=interp(neff_mode2,wavelength_mode2,wavelength_mode1);<br>plotxy(wavelength_mode2,neff_mode2,wavelength_mode1,neff_mode2_new,”wavelength”,”neff”,””);<br>legend(“old data”, “interp”);<\/p><p>This will interpolate the data of mode 2 to the wavelengths of mode 1 so that the effective indices of both modes correspond to the same wavelength points. The plot is suggested to check if the interpolated values are ok compared to the calculated ones.<\/p><p>Best Regards,<\/p><p>Afroditi<\/p><\/p>\n","protected":false},"template":"","class_list":["post-343816","reply","type-reply","status-publish","hentry"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
