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 colleagues
By direct modulation of a directly modulated laser by a sine signal, we get multiple coherent carriers as shown in upper spectrum analyzer. In the same, way on direct modulation of a VSCEL as shown in lower plot in attached figure, i do not get multiple carriers. Please tell me what is the issue and how to correct it.
I will be highy obliged
Regards
Dear Muhammad,
you have to be careful when setting the VCSEL. The modulation peak current setting affects the relaxation oscillation of the VCSEL and the modulating signal frequency affects the VCSEL output signal. It can be distorted after 2.5Gbps.

Please sir tell me, in order to operate VCSELs like DMLs, we have to find its LI characteristics curve and then bias it at the half of the middle point of the LI curve?
Sir i have drawn a LI curve at 1 Gbps data, Modulation peak current =10mA, Bias current sweeps from 0 to 25mA. I gets a circular type curve as shown in Fig attached. How to get a linear straight curve like DML laser so that VCSEL can be biased at middle of this linear region?
Dear Muhammad,
you may use the measured VCSEL because it give more freedom to control the laser specs.
Regards,
Ahmad
ok sir thanks
