Brief
This master's thesis presents the design, fabrication, and characterization of novel tapered optical fiber devices using an integrated molding process and a newly developed drawing system, aiming to improve performance and reduce connection loss for various fiber optic applications.
Summary
This master's thesis focuses on the design and fabrication of novel tapered optical fiber devices using a newly developed integrated molding process and drawing system. The goal is to reduce connection loss and improve consistency compared to traditional methods. Key achievements include the design of non-circular mode field converters (elliptical and triangular) based on double-clad fiber tapering, a mode controller for multi-core to few-mode fiber utilizing the fading core principle, and the successful fabrication of a seven-core fiber fan-in fan-out device using the new system. The research validates the feasibility of these novel devices and the drawing system for various fiber optic applications.
