Postprocessing (wet-etching) of hollow-core optical fibers for enhanced transmission
Unlike the fibers we use today, hollow core fibers can transmit light in the ultraviolet region. However, they cannot be used efficiently due to existing resonance wavelengths where signals are lost. This project achieved a broader transmission band in the ultraviolet to infrared region by imp...

| description | Unlike the fibers we use today, hollow core fibers can transmit light in the ultraviolet
region. However, they cannot be used efficiently due to existing resonance wavelengths
where signals are lost. This project achieved a broader transmission band in the ultraviolet
to infrared region by improving a wet-etch post process. A lower range of resonance
wavelengths was achieved when the fiber capillaries were sealed, flow rate modified and
etched from both sides. The principle of selectively warming the fiber, adding hydrochloric
acid, and fiber annealing were discussed. This study contributes to the development of
optical fibers and their applications in the ultraviolet region. Although the transition to
hollow core fibers will be gradual, it possesses a high potential to be widely adopted. Hence,
it will be beneficial for continuous further research in this area. |
