This chapter presents the fabrication and modal characterization of flat fibers, a specialty optical fiber which has the advantages of both planar waveguides and standard optical fibers. In the introduction section, the demand for flat fibers is discussed including its applications. The main text of this chapter discusses the drawing process of flat fibers including issues such as flat fiber drawing repeatability and drawing of flat fibers with different dimensions. Next, the modal characterization of flat fibers is discussed, with a focus on the light propagation in flat fibers. Both simulation and experimental results show that the light propagation in flat fibers is inherently multimode propagation. However, it has been shown experimentally that adding two defect eyes at the sides of the core could produce flat fibers with single-mode propagation.
