In this webinar hosted by the OSA Fiber Modeling and Fabrication Technical Group, Dr. Lei Wei from Nanyang Technological University will introduce the design and fabrication of advanced functional fibers, including both material selections and fabrication challenges. Advanced functional fibers are fabricated from materials with disparate optical, electronic, and mechanical properties using scalable preform-to-fiber processing. This research field is at the crossroads of many disciplines, including optics, materials science, nanotechnology, and fluid dynamics.
During the webinar, Dr. Wei will present three different stories reflecting the sophisticated functionalities that have been achieved at fiber lengths and uniformity. The first story is the demonstration of a zero-angular-momentum microfluidic laser with purely radial emission. This new capability, implemented monolithically within a single fiber, presents opportunities ranging from flexible multidirectional displays to minimally invasive directed light delivery systems for medical applications. The second story is the demonstration of a silicon nanosphere fabrication process by continuously feeding a silica-cladded silicon-core fiber into a flame to harnesses the Plateau-Rayleigh capillary instability. The third story is the demonstration of intrinsically produced, electrically connected, optoelectronic devices in a silica fiber with the integration of crystalline semiconducting material and metal electrodes in a precisely defined metal-semiconductor-metal architecture. At the conclusion of the webinar, other fabrication approaches and applications will be discussed.
