Brief
This doctoral dissertation theoretically investigates the design of novel microstructured fiber (MSF) devices, such as refractive index sensors, polarization filters, and polarization beam splitters, achieved by incorporating functional materials into their air holes.
Summary
This doctoral research focuses on the theoretical design and analysis of novel microstructured fiber (MSF) devices, specifically refractive index sensors, polarization filters, and polarization beam splitters, by incorporating functional materials like gold nanofilms and liquid crystals into their air holes. The study utilizes the full vector finite element method for simulations, aiming to overcome limitations of current MSF devices and provide theoretical support for optical fiber integration technologies. The research acknowledges the lack of experimental validation and proposes future work on fabrication and multi-functional devices.
