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.

I am attempting (rather unsuccessfully) to simulate a simple OOK transmitter with a homodyne receiver. However, I do not see any difference when I use a local oscillator at the PIN photodiode to perform the detection – as opposed to a direct detection method.
I am using the “Polarization Combiner” in OptiSystem to combine the local oscillator carrier wave with the signal-bearing CW right before the PIN (photo attached). Should I be doing this differently?
Does anyone have any ideas of where I may be going wrong on this simulation? Any help would be greatly appreciated.
I don’t think the polarization combiner is the right tool for the job here. I am not familiar with OOK coherent detection techniques, although it looks like the MZM you are using is also acting as a phase modulator, so it looks like some kind of PSK. Anyways try the 90 degree optical hybrid found in the Receivers Library/Optical Receivers.
I think this structure is generally used for coherent detection, if you are not familiar with the component I would direct you to one of the sample files in the Advanced Modulation folder to see how you could connect it up to photodetectors. For example the “50 Gbps Coherent QPSK_Trans_detail with DSP” in the Advanced modulation systems\PSK systems\QPSK folder. In this example they don’t actually use the 90 degree optical hybrid component, but they have explicitly made it out of cross couplers and phase shifts so you could just copy that as well.
Hope this helps!
