ParticipantHello,
I am new to the forum and I just want the most appropriate answer to my question..
Can anyone tell me the difference between optigrating and fiber bragg grating ? Is there really the difference between the two ? I somewhere read they are the same ?
Thanks and Regards

ParticipantHi Deepak,
OptiGrating is a wider (more general) term for optical gratings used in literature. It includes gratings for different waveguides structure (cilindrical, slab, etc.) and gratings with different profiles (fiber Bragg or some other kind)…. I hope this helps

ParticipantHi Deepak Jha
As far as i understand you have missed a very important understanding difference of the two. Optigrating is a tool while fiber bragg grating is a device that can be used in system design. Although optigrating tool is used to fabricate the grating. I hope this will help you in distinguishing the two.
ThanksAll the best

ParticipantHello Deepak,
I agree to most of what Kanwarjeet has said. This is the basic difference in two no need to confuse yourself.
Thank you

ParticipantHi Deepak,
No they are not the same it has been very rightly said by kanwarjeet that Optigrating is a tool while fiber bragg grating is a device that can be used in system design. Although optigrating tool is used to fabricate the grating..

SpectatorHELLO DEEPAK JHA..
I completely agree with Kanwarjeet. There is definitely a deifference between the two as mentioned by him..
That shall help you.with Regards

ParticipantHi Deepak,
As we know that Light signals at wavelengths other than the Bragg wavelength, which are not phase matched, are essentially transparent. A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others.
The non-uniform (chirped and apodized) grating is divided into Number of Segments uniform gratings. The coupled mode theory is used to calculate the scattering matrix of each uniform segment, and the spectral response of the whole grating is found by connecting the uniform segments using the transfer matrix theory. The apodization functions are Gaussian and Hyperbolic tangent. The chirp functions which is used as follows:
Linear, Quadratic, Square Root, Cubic Root.-

I think he wishes to know the basic difference between the two. I guess you are going for depth.

ParticipantHi,
I also wish to add about optigrating.
OptiGrating uses the Coupled Mode Theory to model the light and enable analysis and synthesis of gratings and conference publications which reference the use of OptiGrating.
Please refer to following links to get more about FBG and grating:

Hope this will help you.-

ParticipantHi Deepak,
Fiber Bragg Grating is the application of Optigrating. The link which is depicted below states it.
https://optiwave.com/category/products/component-design/optigrating/optigrating-applications/
A complex grating is approximated by a sequence of uniform segments, and analyzed by connecting the segments with the well-known Transfer Matrix Method.
There are many applications of optigrating are:
WDM add/drop, narrow and broadband fiber and waveguide filters
Fiber Bragg reflectors
EDFA gain flattening elements
Dispersion compensators for fiber communications
Sideband suppression using grating apodization
Fiber and waveguide sensors
Long Period Gratings with coupling to cladding modesHope this will help you to understand.

It should be very clear for Deepak now to see the distinction between the two. it shall have helped him. It was rather a Good discussion. May good points were being discussed yet the question was basic.
