Optiwave software can be used in different industries and applications, including Fiber Optic Communication, Sensing, Pharma/Bio, Military & Satcom, Test & Measurement, Fundamental Research, Solar Panels, Components / Devices, etc..
OptiSystem is a comprehensive software design suite that enables users to plan, test, and simulate optical links in the transmission layer of modern optical networks.
OptiSPICE is the first circuit design software for analysis of integrated circuits including interactions of optical and electronic components. It allows for the design and simulation of opto-electronic circuits at the transistor level, from laser drivers to transimpedance amplifiers, optical interconnects and electronic equalizers.
OptiFDTD is a powerful, highly integrated, and user friendly CAD environment that enables the design and simulation of advanced passive and non-linear photonic components.
OptiBPM is a comprehensive CAD environment used for the design of complex optical waveguides. Perform guiding, coupling, switching, splitting, multiplexing, and demultiplexing of optical signals in photonic devices.
OptiFiber The optimal design of a given optical communication system depends directly on the choice of fiber parameters. OptiFiber uses numerical mode solvers and other models specialized to fibers for calculating dispersion, losses, birefringence, and PMD.
Emerging as a de facto standard over the last decade,OptiGrating has delivered powerful and user friendly design software for modeling integrated and fiber optic devices that incorporate optical gratings.
Modal analysis is a pivotal component of modelling optical structures. OptiMode serves as a robust CAD platform for the design and modal analysis of waveguide structures.

When we increase the transmitted power the BER decreases. which is general behaviour.
But
Please guide me that why after a certain input power the BER starts increasing???
As shown in figure attached: After 9 dbm the BER starts increasing while with the increase in Power.
If you are using a fiber,This is right, because The non-linearity start to appear as the power increased,but in your curve the non-linearity appeared late may be the effective area of the fiber is large or nonlinear refractive index is too small.
Cheers,
Abdallah
What kind of optical fiber are you using for your experiments? If it a special design with the large mode effective area then I agree with Abdallah (if the number of channels and the bit-rate are the same in both cases).
If you are not studying non-linearity in your research and it has no great effect in your system,You can disable it from fiber properties.
and the fiber will work as a linear medium and you’ll not see the knee in your results.
regards,
Dear Abdullah when u start increasing power the non linearities of fiber start increasing in the same manner which results in poor BER.
Abdullah non linearities always present in fiber because fiber don’t have ideal properties but if u don’t require to deal with non linearities in ur work then u should disable them.
We can’t remove non-linearities from the fiber, since its initial property which takes place for powers higher then threshold (depends on the type of non-linearity). Therefore, we should keep that in mind when we disable them “artificially”.
You can minimize the effects of non-linearity in that topic I managed to decrease the effects of non-linearity: https://optiwave.com/forums/topic/project/, but disables it manually I believe it would not be appropriate, as it depends on what you’re working on, ideally you decrease this kind of loss, that would be the more correct.
