Summary
This doctoral research explores the use of femtosecond laser and fused tapering micromachining techniques to fabricate and apply space division multiplexing (SDM) fiber optical devices for sensing and communication. Key achievements include an improved seven-core fiber displacement sensor with a reduced dead zone, parallel Fabry-Perot interferometers in multicore fiber for simultaneous temperature and strain measurement, a mode selective converter for few-mode fibers, and a high-performance photonic lantern fabricated from a fiber bundle.
