Bend-resistant high-resolution imaging optical fiber
No full textWe report design, fabrication, and characterization of bend-resistant high-resolution imaging optical fiber comprising over five thousand cores. The fiber is made of low-cost commercial-available H-ZK9B and H-K3 glasses which gives rise to a maximum numerical aperture up to 0.552 at 750 nm wavelength. The multi-stacking arrays of three-sized cores can effectively suppress the core-to-core crosstalk and raise the bend resistance. No degradation of imaging is demonstrated at a bending radius less than 2 cm and at an extensive wavelength range from the visible to the near-infrared, showing a substantial improvement over commercial state-of-the-art fiber bundles
Study of microbubble defects in high-NA silicate-glass multi-core imaging fibers fabricated by the stack-and-draw method
No full textThe fabrication of multicore imaging fiber (MCIF)/fiber bundle by the stack-and-draw method is favorable to achieve a hyperfine spatial imaging resolution without the rise of lattice defectw, such as core breakage and dislocation. MCIFs made of silicate glasses as host materials usually present a high numerical aperture (NA), lower bend loss, and low inter-core crosstalk, giving an excellent imaging capability. In this paper, we focus on the microbubble defect (MD) in the high-NA silicate-glass MCIF fabricated by the stack-and-draw method. MDs are a type of local defect in a scale of micrometers or smaller, distributed randomly along the fiber length. Some MD would cause the abrupt variation of the core shape in the neighbor, which gives rise to a local scattering loss up to 103 dB/m according to the numerical simulation. The origin of MD is still uncertain, and our investigation shows that MD could possibly be mitigated or even eliminated in principle by minimizing the difference in softening the temperature between core and cladding glasses.
