Photonic Crystal Fiber infiltrated with anysotropic material

The question is easy, but I don´t know the answer 😛
It is possible to make a model of a PCF selectively infiltrated with an anisotropic material?

Hi,

Are you looking for some kind of diffusion process (as the term “infiltrated” would imply)? If it’s the case, then OptiBPM / OptiMode would be a good match.
If you just want to change the refractive index of the PCF “glass” material, you would need to define a dielectric material in the profiles and materials designer and check the “anisotropic” box. You will then be able to input diagonal elements of the permitivity tensor.

To add to Aurelien’s answer: We have a mode solver in OptiMode that can accommodate anisotropic material. It will be possible to draw a photonic crystal structure and include anisotropic materials in this. When the anisotropic mode solver is called, it will find the modes.

Hi,
please could we do the same procedure if we want to design HC-PCF filled with material with some kind of material?
thankx

It depends on the details of the design of the Photonic Crystal Fiber. We can simulate some of them, but not all.

Thanks for your help.
The material I was thinking is a Liquid Crystal, a birrefringence material. Could it be possible to made a simulation with a PCF infiltrated with this material and study the change of the guiding properties (modes) due to the change of the orientation of the molecules?
