      Hey everyone, I actually need an information. I have been using FDTD for some works related to Gates. Well I have been facing a problem in setting the length i.e. the length between two waveguides if at all its in ‘Y’ shaped. Here is the file attached below.

      Hi,

      Are you using OptiFDTD to simulate your problem? Is so, could you attach your project file so I can have a look? Which length are you referring to?

      Best regards

      Hey Aurelien,
      Yes I am using it but cant figure out, if at all its completed successfully I will definately attach the file. Here lenght I meant is the distance from the starting point of the Y shaped waveguide till the junction where the two straight line joins at a point to form the desired Y shape.

      Regards,
      Saurav

        Hi Saurav,

        Aurelien is away for the week, but I can help answer your question. We have a tutorial at:

        PBG Layout

        That could be a good place to learn how to edit the layout and introduce defects. To make that segment longer, you would just need to start the the points A and B farther apart and maybe increase the simulation domain.

        Hope this helps!

      Its is dependent on the photonic crystals size and lattice constant.
