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.
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 am going to test the modulation bandwidth of RSOA. I upload the setup. the issue is that I cannot get 1GHz signal after PD when I use 1GHz sinewave to modulate RSOA.
as you suggested, i can detect the peak around frequency. now the problem is the modulation bandwidth unlike real RSOA which show us low pass property. any suggestion on that? thanks
In your particular example, I think the cutoff frequency is much higher than the values you swept. Try increasing the frequency to >10 GHz, I achieved a low pass filter shape. Although it was not perfectly flat.
Thank you so much for your reply. The modulation bandwidth is generally less than 2GHz in a real RSOA component. the shape is going high from 100 MHz, may be increased by more than 5dB, then going to drop, even if I changed some parameters.
OK then the problem is something else! Do you have a paper with the results you are expecting? Showing the cutoff frequency and containing information about the RSOA parameters.
The OptiSystem team is determining whether the gain is a problem with the default parameters not corresponding to a peak gain at the default wavelength. For now can you please try the Linear or Lorentzian gain approximations for the material gain in the Enhanced tab.
I tried the linear gain approximations, which is generally used for bulk RSOAs. However, the results are not correct. I even cannot get sin waves . I haven’t figured out where the problem is. could you please help me?
Damian, thank you so much for helping me lots on the rsoa module. The modulation bandwidth is still so high, more than 6 GHz when I used the linear gain approximations. I tried to change some parameters. however I havent figured out. any suggestion?
finally, I got the more reasonable modulation response. however the curve starts rising around 2.4GHz as shown in fig. some parameters may not be proper.
I think I used most of the parameters in the document you posted, you could also try the Lorentzian qpproximation. It is hard to say though since I only have one page to work from and it doesn’t say what type of model it is using. You can look at our help file which is accessed by the component properties window and see the background theory and references we use. You should be able to match the parameters with those from your reference.
