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.

I try to compensate second and third order fiber dispersion in the frequency domain, the frequency domain filter works well at 25 Gbaud/s and gives results close to compensation using DCF but when increasing symbol rate to 50 Gbaud/s there is a clear difference between compensation using DSP and DCF, is there a problem in this method?
Hi Fouad, When I ran your simulation, I encountered an error stating that it couldn’t load(‘D:\qpsk data\I_comp1’). If there is another Matlab file that you have not attached, please attach it. Otherwise. could you give an explanation about this? Thank you.
I attached these files, that load In-phase and q-phase components from Matlab to optisystem also the binary data, QPSK symbols for calculating BER if needed and you may need (Inphase_comp_tx_for_Q-factor)that contains In-phase component with no biasing or amplification (i.e. constellation points at [-1+1j 1+1j -1-1j 1-1j]). you could use these files and change the paths or use your own QPSK TX and RX but you will need the last two matlab component(specially matlab component 2) to compensate the dispersion.
attached here a file comparing the performance of DSP and DCF, the difference in the performance can be seen from the constellation visualizer.
i don’t know where is the problem, the frequency domain filter just multiply the signal by the conjugate of {exp(j*[(beta2*omega^2/2)+(beta3*omega^3/6)]), beta2,3: second and third order dispersion, omega: angular frequency} to compensate dispersion.
