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 try to get constellation diagram for 16 QAM using OFDM 4 QAM example. (OptiSystem 14.2 Samples\Advanced modulation systems\OFDM systems\Direct Detection OFDM 4 QAM)
By using this example, I change the bit/symbol from 2 to 4 to get 16QAM.
But constellation diagram at OFDM demodulator is not correct.
Can some help to explain why cannot get correct 16 QAM constellation diagram?
And how to get the correct 16 QAM using this example? attached is the result for 4 bit/sym.
Hi Nadzreen, can you attach the your optisystem project file.osd ?
if you run the OFDM system with QAM modulation, you must configure the symbol rate and reference bit rate, not only on the QAM Modulator, but also on OFDM Modulator. After that, When you used the BER TEST set, there are many parameter sets that must changed.
I Hope this project can give you the solution. But this project not give us the BER Value.
On this project, we must change the configuration of the phase value on the Quadrature Demodulator for the variation of optical launch power (CW Laser) and optical fiber length so that we can the good constellation.
Hi Nadzreen, please try this scheme if you want to know about the characteristic of direct detection mechanism.
Based on this simulation, you can find that The direct detection mechanism is not appropiate for high modulation e.g 16-QAM. The constellation is not good and have the High BER. You also using the high power for CW Laser, and you cand find the effect of the phase set and quadrature demodulator.
