Thank you Damian…

Hello Miguel, I have gone through all the parameters of the attached file and I found out that in profiles and materials the 2D profile defination should be same as that of 3D. Even the material should be same in wafer properties. You can just check it out.

Hello Himadri, Well are you using optiFDTD to simulate your structure or some other software. Attach the structure so that I get to know.

Hi Harikiranjeet, as far the difference is concerned they are different in geometrical shape and also with respect to irreduicable Brillouin zone along the k vector path. Simulation is you have to choose what type of crystal you want and accordingly create the defect to create any sort of waveguide. Well I would say the hexagonal arrangement is much better for propagation of modes and output power is significantly better and thus the loss is.

Thank you

Thanks again. But hey Ravil have you got any book with you named -“Photonic Crystals, Theory, Applications and Fabrication by Dennis W PratherC”. If so can you just attach the pdf file.

[Saurav ChandaParticipant]

Thank you Ravil & Damian. It simply worked.

[Saurav ChandaParticipant]

Is area detector = observation point in optiFDTD?

[Saurav ChandaParticipant]

Hi esakkimuthu,I hope there is no such option only you can vary the power level thats it.

[Saurav ChandaParticipant]

Any idea please forward.

Hello Perveen, I was busy a bit so couldn’t catch you. So what all are the problems which you are facing? You can mail me at souravchanda72@gmail.com.

Thank you

Under the FDTD-Nonlinear folder right click and create a new Material. From there you can choose whether it is a 2nd, 3rd, Kerr … type material. Since you only have the nonlinear index that means to me that you would be making a 3rd order material. You then just need to convert the index to a susceptibility. You can find the calculation on the web.

Hi Aurelien,
Yes you can check the paper “PHYSICAL REVIEW B VOLUME 60, NUMBER 8 15 AUGUST 1999”. Here I am attaching an image file, you can check it out.

Thanking you

Great.

[Saurav ChandaParticipant]

Yes you got it.

Hey Siva,
I have worked a bit on it. Can you please provide me with the files(XOR, AND & OR) so that I can cross check it.
