Ok. Thnks, I will visit the Link you gave and post questions there.

[Dr. Subhashish TiwariParticipant]

ok….Sir

[Dr. Subhashish TiwariParticipant]

Ok. Thanks

[Dr. Subhashish TiwariParticipant]

I think it should be available for trial also.

[Dr. Subhashish TiwariParticipant]

I downloaded the Trial. Can I get the tutorials about how to use OptiBPM, also OptiFiber ?

[Dr. Subhashish TiwariParticipant]

ok ..

[Dr. Subhashish TiwariParticipant]

You need ?

[Dr. Subhashish TiwariParticipant]

Ok. I will read more about Optigrating. I have one more question to you Damian – If I have to taper an optical fiber (plastic optical fiber) and use the tapered region for sensing, can it be performed in OptiFTDT ?

Thanks

[Dr. Subhashish TiwariParticipant]

it is of 7-8 mm.

[Dr. Subhashish TiwariParticipant]

which software could do that ?

[Dr. Subhashish TiwariParticipant]

Yes Damian, the tapered fiber is separate, the tapering is done on plastic optical fiber.

Grating is not involved in this. An image of taper is attached below. It may be from 7- 13 mm.

[Dr. Subhashish TiwariParticipant]

Damian, as you said ” using an Observation area it is you could detect the transmission as a function of wavelength through a fiber”. Where to find the fiber first for modelling.

[Dr. Subhashish TiwariParticipant]

I worked on photonic crystals simulation in 2-D. For optical fiber, do the linear waveguide has to be used as optical fiber.

[Dr. Subhashish TiwariParticipant]

If any opti-designer file based on optical fiber is there, please provide me.

[Dr. Subhashish TiwariParticipant]

Hi damian,
Please answer my query soon.

[Dr. Subhashish TiwariParticipant]

Perhaps you mean the cross-section of fiber

[Dr. Subhashish TiwariParticipant]

Sir,

I imported the .f2d file in Matlab and theresult is as shown in the image attached below. I am not able to understand, from where to use the ‘str2double’ option as it is not being shown.
Also please let me know, how to plot now the values of the two columns in Matlab.

Thank you

[Dr. Subhashish TiwariParticipant]

It is re-attached

[Dr. Subhashish TiwariParticipant]

In PNG

[Dr. Subhashish TiwariParticipant]

Also Sir, Can i use Origin software also to import from Optifdtd.

Thanks

[Dr. Subhashish TiwariParticipant]

I have plotted in matlab, now i will try in origin.

Have you plotted in matlab Perveen ?

[Dr. Subhashish TiwariParticipant]

ok, thanks..

[Dr. Subhashish TiwariParticipant]

Sure David,

A fig attached below gives a cross section of PCF. The air-holes are arranged in a hexagonal lattice configuration while input field is given in core (center) of the structure. There are refractive indexes of core and cladding material separately defined. Such as if it is a solid core , then n=1.45 (Si) , the air cladding holes will have n=1.0. Now if we consider the refractive index of whole structure, it is said to be dependent on the input wave’s coverage in cladding area, known as Effective Refractive Index (Neff). Through this term dispersion is calculated for a fiber. I wanted to know the option of calculating this Neff in Optifdtd.

Thank you

[Dr. Subhashish TiwariParticipant]

Hey DCM,

Please see the attached bandgap picture, obtained after running the PWE bandsolver. Now what I have to do.

[Dr. Subhashish TiwariParticipant]

Hi Saurav,

I saw the Igor V Sukhoivanov profile, can you specify which paper of him would help in finding Neff.

Thanks

[Dr. Subhashish TiwariParticipant]

Is the book name “Photonic Crystals: Physics and Practical Modeling (Springer Series in Optical Sciences)”

Thanks

[Dr. Subhashish TiwariParticipant]

I downloaded that “ebook”

[Dr. Subhashish TiwariParticipant]

Nope, I am using Optifdtd 11.x , 32-bit.

[Dr. Subhashish TiwariParticipant]

Using Windows-7 , 32 bit

[Dr. Subhashish TiwariParticipant]

The observation line panel is attached below.

[Dr. Subhashish TiwariParticipant]

Ok Sir, I will try the same.

[Dr. Subhashish TiwariParticipant]

Have you worked on resonators or know someone having idea about this.

[Dr. Subhashish TiwariParticipant]

Thanks Damian !

[Dr. Subhashish TiwariParticipant]

Thanks Bryan. It’s a great feature enabled.
