What's happening ? Please share your thought.
In the Spatial VCSEL: if you excite 2 modes (LG00 and LG01) then you divide the power ratio between them equally as (0.5 0.5) or unequally as (0.8 0.2), The value of the power coupling coefficient at the Multimode fiber are the same?
In another word, why the power coupling coefficient values are the same regardless different power ratio?
Is that logic? Please share your thought?
