This master's thesis proposes and simulates a multi-channel orbital angular momentum fiber coupler designed using traditional methods and introduces a neural network approach to predict its optical characteristics for improved design efficiency.

Summary

This master's thesis designs a multi-channel orbital angular momentum (OAM) fiber coupler using computer simulations based on "phase-shifted coupling" theory to generate different OAM modes from multiple channels. To improve design efficiency, it also proposes and tests a neural network approach to predict the coupler's optical properties like coupling wavelength, demonstrating faster and more efficient results compared to traditional simulation methods. The research aims to advance OAM fiber communication technology.
