Hello all,
I tried using the donut mode generator and transmitted one mode (0,0) through the Measured index multimode optical fiber and I got multiple modes at the output of the fiber. Totally I got 0 to 49 modes. When I saw the spatial visualizer report calculation, I got list of output nodes and power of the nodes. But when I viewed the output in spatial visualizer, mode 0 and 1, mode 6 and 7, mode 27 and 28, looks like same at the output screen.
Can anyone please clarify ?
I am attaching the spatial visualizer report calculation and a picture of the file and osd file.
And also I used the single mode fiber and linear multimode fiber and I got the output.
In single mode fiber, I got only mode 0 as output even when I transmitted more than one mode.
In multimode fiber, I got the output modes what I have transmitted at the input.
When I saw the donut mode component description, it converts the single mode into multiple modes.
This multimode conversion is happening at the measured index multimode fiber.
Why this conversion is not working in Linear MMF and SMF?
Thanks in advance.
