Design multivore photonic crystal fiber

[Nashwan AL SAMMANParticipant]

Hello everybody 🙂
I used BPM simulater and I design solid core PCF but within short distance reach to 10cm to 100 cm , that takes looong time to finish simulation , how can I simulate looong distance and calculate the dispersion and coupling efficieny,

Also Can I multicore PCF model in long distance ??

Thank you for your help

There might not be an easy way to simulate this long a of fiber. The BPM method is good for micrometer to millimeter range, but the larger a simulation domain the longer the simulation will actually take. You might need a very powerful computer!

thank you Mr. Damian Marek ,
do you have any suggestionsx to use any other softwares or any other tool to design long Multicore fiber
than

I need to simulate multicore pCF , can BPM manage to simulate multicore PCF by modifying the shape. parameters ?
How to find out the coupling eff. using monitors. is it accurate results, ?
thank you sir

Like Damian has said, the BP method is suitable for propagation of length up to several thousand times the wavelength. (So for optical wavelengths, millimetre lengths of propagation). For longer propagation, you’ll need to use other methods. There is probably no commercial software for that simulation, but you can probably make a suitable model yourself. For this problem, I recommend non-orthogonal coupled mode theory. When solving by that method, you will need to know details of the optical properties of the waveguide, such as modes, modal index, modal field pattern. You’ll need to calculate overlap integrals of the optical modal fields with the coupler geometry. Optiwave software can help by finding the modes and also with overlap integral calculation. We don’t have the complete solution for you, but our software can help with the hardest part: finding the modes.
