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 want to simulate a type of LPFG, but I do have a question about the input modes. As shown in the attach file, there are a lot of modes propagating within the fiber core, and we can choose which mode(or modes) as the input modes. Different input modes, however, will result in different transmissions.
I am really confused about the input modes. I do not know which mode should be chosen as input modes and why.
OptiGrating gives you the option to use a higher order mode as an input mode, if desired. For an application such as yours, you may not have any use for them.
As you said, I use a single higher order mode as an input mode, but OptiGratings still cannot get the ideal transmission spectrum when I simulate LPFG. However, it will show good spectrum if I use a set of modes as an input mode. But I still do not understand why I should choose those modes as an input mode. For a single mode fiber, it has only one mode propagating within the fiber core region. I do not know the reason why there are so many modes after recalculating modes on the step of Modes Parameters.
OptiGrating will let you select only one mode for input. You can select as many modes as you like for the simulation. If the grating causes coupling from the input mode to any of those selected modes, the power lost from the input mode to the selected mode will be taken from the transmission spectrum of the input mode. The interaction will be apparent from observing the transmission spectrum of the input mode. The graphics do not permit display of all selected modes. If only two modes are selected, all 4 curves will be shown (forward and back waves of each of the two modes). If more than two modes are selected, only forward and back waves of the input mode are shown.
