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.
OptiInstrument addresses the needs of researchers, scientists, photonic engineers, professors and students who are working with instruments.
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.

Dear all,
I am working on a project with M-QAM OFDM signals and RoF.
My current problem is with 64QAM signal. I get the constellation, which looks like very good, but it is not ok when I compute the EVM by MatLab. The EVM is higher than 30%!
To compute the EVM on MatLab I use to rescale the constellation. For 4, 16QAM signals work super great. The EVM is always as I expected. However, I cannot know what happen with 64QAM. The constellation, after signal processing on MatLab, looks like a left-shifted. I know that the rotation appears with fiber… but there is no fiber! I have also checked the signal at baseband and I found a peak in the center of data band… I also do not know why it is there… because when I use 4 or 16QAM the baseband data is great.
I know that I have to move OFDM OS12 to new OFDM component, but I need some results now and I do not have lot of time to change everything. I will do it very soon.
Could anyone help me?
Best regards,
Luis
Hello Luis,
I’ve replied to your enquiry through email. There were few issues related to the settings of the Quadrature Modulator gain and the LP Cosine Roll Filters after OFDM cut off frequency.
Regards,
Ahmad
