How to draw a 3D elliptic cylinder?

[Christopher Dirdal]

Hi!

I am interested in making elliptical holes in a slab and simulate transmission through the slab. The 3D cylinder drawing tool gives circular holes, and I am unable to rotate the elliptic waveguide drawing so that it faces the z-direction…. Any suggestions?

Hello Christopher,

By “faces the z-direction” I am going to work under the assumption that you mean the elliptical cross section is in the XY plane and the waveguide runs along the z axis.

The best way to set this up is to add a fiber profile through Profile Designer with your desired major and minor axis. then create a linear waveguide along z and assign the fiber profile to this waveguide. I have attached a picture of a design that has the elliptical waveguide you are referring to and the waveguide I am describing on the left.

Is this what you are looking for?
