Hi David Sir,By mistake I forgot to attach the .zmx file, Sorry for that, I am attaching now.
In non-sequential mode, using two coaxial cylinders to represent the core and cladding should work okay for simulation of a multimode fiber (MMF), but there are a few details to take into account. First, in the layout spreadsheet, the cladding cylinder should be listed before the core cylinder. That way the nesting rules associated with object placement will ensure that the core replaces the appropriate portion of the cladding cylinder. Here’s an example using the NA = 0.22 core and cladding refractive indices with a simple 0.20 NA source. The coupling efficiency is 92.5%. The 7.5% loss is simply Fresnel reflection from the input/output surfaces. This raytrace was done with ray splitting (and hence polarization) turned on, as well as using a linearly polarized source beam. If the fiber NA is increased, the coupling will remain unchanged as expected since all of the non-reflected rays are being guided. However, if the NA of the source is increased to 0.30, you can see claddin
Thanks a lot for your comment.
Hi David..Thanks for help…This problem was coming after I clicked “yes” button by mistake when zemax asked me “ Do you want to overwrite the Coating file” while opening a sysem design in Zemax. But now it is fine, thanks again for your help.
By mistake I have attached a wrong file, please ignore that file.I am attaching the right file in this post.Thank you.
