Photonic Crystal refractive index Setting

[Dr. Subhashish TiwariParticipant]

I have few questions. Admin or any other expert can please reply.

1. I am making an optical switch (reference paper attached below) in which non-linear material photonic crystal rod has to be added in the waveguide alongwith other silica rods. What is the option to edit the refractive index of the rods.

2. I have to get the outputs in the form of band gap structure graphs and Transmittance , Reflectance graphs. Is there any option to plot these graphs.

Please reply as soon as possible.

Thank you

Hi,

In the Profile Designer you can create and define materials. Later when creating the photonic crystal structure you can choose which material to use.

There is a bandgap solver included with OptiFDTD, so you could get the bandgap graphs from there. You can also you Observation Areas/Lines to determine the reflectance and transmittance vs wavelength.

There are some tutorials on these subjects at the following link:
