Split Step Fourier Method

Simulate Pulse propagation in Fiber optics

Description

This M-File solves Nonlinear schrodinger equation and display the results in 3d graphics along with it the Pulse broadening ratio and phase shift has also been calculated and displayed.

• MATLAB release: MATLAB 7.0.1 (R14SP1)
• Other requirements: Nil

well done. im doing something related this for my final year project and this is a huge help.. Thanks
i have some problems simulating self-phase modulation and cross phase modulation in matlab. please if u can provide some codes for that it would be great. thanks again!

[Yangyang Liu]

Good work. The double loop really isn't necessary though.

thanks a lot! its is very ver helpfull

Hi Mudassir, I would like to have a one question. If I consider only nonlinear effect in this code, the shape of pusle in time domain does not change right?...theory says that nonlinear effects has direct influence on pulse in spectral domain (spectral broadening), but inderect influence on pulse shape in time domain. So the pulse shape in time domain after pulse propagation is not changed. it is true or not ?...thank you

Hi Mudassir, I am navaneeth, doing my maters....I have a roadblocks in my masters project with the nonlinear effects in optical fiber. I would need your help to clear those roadblocks.. If you can help that would be great...and will be very thankful to you.....

Fine work. Users may be interested in checking File ID: #14795

This is a good program. However if you can include code involving the Higher Order Nonlinear terms that would be much helpful.

[Yang kangwen]

Thanks.

[wei xingchun]

Thanks. It's very useful.

it is correct, i made a mistake , it is /dt. comment, his code is not normalized expression

I think the definition of dw dw=1/l/dt*2*pi; is wrong.
it should have times dt rather than devided by dt

[Qunfeng Shao]

I found somthing wrong in this script.
spectrum=spectrum.*exp(-alph*(h/2)+i*b2/2*w.^2*(h/2)) ;
here,the alph should be alph/2.

can u provide code for Radio over fiber system or any code via which I can calulate BER for transmission of RF 2Ghz frequncy on fiber using 1550nm laser using single mode fiber

This is a good program. However if you can include code involving the Higher Order Nonlinear terms that would be much helpful.
