Brief
This Master's thesis investigates the theoretical analysis and experimental study of tunable few-mode fiber couplers fabricated using the side-polishing method to achieve adjustable optical signal splitting.
Summary
This master's thesis focuses on creating tunable few-mode fiber couplers using a side-polishing technique. The author, Yin Xiaokang, conducted theoretical analysis based on mode coupling theory, simulated the coupler's behavior under different fiber parameters like core spacing, and experimentally fabricated and tested a prototype.
