      Hi Yaseen,

      Please refer to page 22 of the manual for more details. In brief, Ind. Mod. (or delta_n) is the index modulation amplitude or the strength of the grating, e.g. peak refractive index change of the sinusoidal grating. Along with the length, It affects the bandwidth and reflectivity of the grating.

      Kid regards,
      Amin
