Conclusions : It is demonstrated that it is possible to code 32
polarizations states over a non-polarization maintaining single-mode
fibre at 633 nm by using an artificial intelligence K-nearest neighbor
algorithm with 4 features and 13 neighbours with an average
assertiveness index of 99.02%. This is a good estimate for applications
in which the angular position of a device needs to be determined and the
information sent through a standard non polarizing fibre.
