Photonic Crystal Fiber Simulation

[Bijan goudarzi]

I go step-by-step the Chapter-17th of tutorial pdf file(attached below) to design a PCF with the same parameters in optiFDTD, but finally the resault is not the same (can not find any mode). What is the problem?

Please attach your FDTD designer file.

Dear Marek,
Here is my layout.

Hi, you refer to OptiFDTD version 8.0 which was released in 2009.

The tutorials available online and in our current products have been updated. Please use a more recent version of the software, for example our free 32-bit OptiFDTD:

Dear Duval,
As you said I used newer version of optiFDTD, for example free 32-bit or free 30-days v12.00 optiFDTD.All is ok by designing PCF structure and exporting refractive index exporting, but the problem is when I go to Mode analysis! There is no mode-solver tools with them. By the optiFDTD 8.0, there is a 3D mode solver (as tutorial refered) and I load my refractive index distribution file there, but there is not such a tool with optiFDTD-32 or v.12! may you guide me?

[Damian Marek]

The 3D Mode Solver was expanded and made into its own application now called OptiMode. You should be able to find the OptiMode designer in your OptiFDTD installation folder.
