I am attempting to model a multi-mode symmetrical slab waveguide using Fortran 90. I am able to produce plots of each optical mode and am then summing them but I am more or less convinced that the relative intensity of the modes is incorrect. I am fairly sure that the error is arising because I...
I have posted this in some other physics forum, however, I have not yet gotten any definite answer. Hope some of you can help.
I have been trying to understand why in a hollow metal tube, the Maxwell equation admit wave solution, and that they are always TE or TM. In all of the textbooks I...
i am now trying to figure out the electro-field around a rectangle waveguide. the refractive index of the waveguide is n1, which is larger than that of the cladding, namely n2, outside. we may regard the waveguide embeded in the cladding material.
as following shown, the waveguide...
