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.

How to calculate the mode field diameter (MFD) of fundamental mode and other modes of a multimode fiber. Is there is any equation. If it is , then can we use it both for step-index and Graded index fibers. What is the method to calculate MFD from the field itself?
You could use OptiFiber to calculate these values over a range of wavelengths quite easily. Generally the mode diameter is defined for Gaussian-like modes as the radius at which the intensity drops to 1/e^2 of the initial value.
I agree that mode field diameter depends on the type of fiber and its dimensions. However, did you really mean that in can go down to um or did you mean nm? Just checking…
um as in “micrometer” 🙂 which is 10^-6 m. So yes, I think that is the general limit for optical fibers. I know that some tapered fibers that have high confinement can reach Aeff of 1 um^2 , which means that the radius is probably <1um but these are specialty fibers. Generally I think nanometer radius modes are quite uncommon.
The mode filed diameter depends on fiber parameters and the operating wavelength. Usually it is just above the core diameter in the case of SMF, So the MFD is in the micrometer range. It can be find out using one equation (w/a)=0.65+(1.619/v^1.5)+(2.879/v^6). This equation may be valid to the fundamental mode of MMF.
My question is what is the MFD of the fundamental mode of OM2 fiber at 1300nm?
Many thanks to everyone for explanations! Damian was right: I interpreted 10 um as 10^(-10) m which is quite low :). Thank you Alessandro for your quick answer! Thanks you Thomas for your explanation!
