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 think something is wrong in the module Optical Receiver in the Optisystem version 13. I test the same project with versions 12 and 13. It is a very simple project with only the fiber atenuation needed to reach the receiver with the same optical power that the aproximate sensitivity of the receiver.
In version 13 the obtained Q is more than 47 and in version 12 is the expected value of 6.
I attach two screenshots with the results obtained with the two versions.
Thank you for your support.
Hi Damian,
This is the osd in 12 version. This file can be opened with both versions. However, if you want, I can make a new one from scratch with the version 13.
Best regards.
I send you the same file in version 13 from scratch.
May be that the origin of the problem is that in version 13 the default filter cutoff was 0.75*symbol rate but I think the correct choice should be 0.75*Bit rate as in version 12. If you filter to 0.75*symbolrate, you lose the signal.
Thanks Damian!
Thank you for these files! I am not sure what is causing this behavior and although you are right about the filter needed 0.75*Bit rate that doesn’t fix the discrepancy.
I’ll ask the OptiSystem team what they make of these results, maybe I am missing something!
I got an answer back from the System team. Apparently a decision was made to change the effective noise bandwidth from a default value of the sample rate to the bit rate. From customer feedback it will revert back to the value of the sample rate in the next release (13.0.2). For now try changing the effective noise bandwidth from bit rate to the sample rate.
