      nw i tried to design for my calculated v-number in stepindex multimode fibre , the data is given,

      core dia-62.5 micrometer,
      core cladding index -1.5%
      core refractive index -1.480
      operating wavelength -1300

      after taking this design into optifibre, i could see lot of modes which exceed my v-number that i have calculated, so what are the optimization need to take for constraining our calculated modes

      The biggest thing you can change is the core diameter. 62.5 um is quite large! For single mode fiber, it is usually less then 10.

      I agree with Damain but also I think the V number is very large and it’ll pass very large no. of modes.

      the core diameter of your design is quite large. try to reduce it and see the number of guided modes again.

      thank to u kang, and which area of u working in optical domain, because if ur area is confine with me we will share our work and put more efforts towards the work
