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 am facing a problem with my system. Whenever I make a duplicate copy of system and simulate it, the results on BER analyzer gets changed. even I have unchecked the random seed generation still the problem persists and I noticed a changes from 0.1 to even 5 in quality factor.
I am not able to make graphs due to this problem. Even I checked in some of examples in Samples the problem lies there also.
What is the reason that when I duplicate a layout or even select all and paste it onto a new layout the results change.
What to do to overcome this problem and make graphs accurately.
I am attaching the file in attachment. Please do reply me fast.
You correctly disabled the generate random seed for the bit sequence generator, but there are other sources of random noise in your system. For example, the Laser and Photodetector PIN.
Thankyou Damian.
It solved my problem. but is it authentic to disable all noises(Signal- ASE, ASE-ASE, Thermal and shot noise) ?
and what is the I have one more doubt regarding it. The noise generation is random. Then why does it not change everytime I simulate the system and changes only when I change the layout?
and What should I prefer? whether drawing graphs with random readings or disabling all the noises and the take the readings?
My simulation changes with each calculation if I have the generate new seed box checked. It might be possible that you are using an older version of OptiSystem?
The variations will become smaller, but how small depends on the actual BER of the system. A noisier system will be more susceptible to random changes in the noise and there will be larger fluctuations in the calculated BER.
Thankyou damian. You are always so very helpful.
It solved the problem. I was missing out the random seed boxes checked in PIN and laser. Thats why I was getting results changed everytime. Now I got over it and getting constant results.
yes GURINDER you have to uncheck the random seed generation not only from PRBS but also from all components like PIN LASER etc. Then you will get constant results to make decisions.
Hello Gurinder,You can make the value of random seed generator zero.If you will have same problem ater setting seed to zero then do same as Damian wrote in previous reply.
@ MohammadMahdi Ariannejad
Please read the discussion above and follow the steps of switching off the random seed generation from generators of random noise.
