New low-loss liquid-core fibre waveguide
Electronics Letters, 8, (15), . (doi:10.1049/el:19720273).
Low-loss liquid-core fibre-optical waveguides having a transmission loss of 10 dB/km has been made using commercially available glass tubing. The loss is less than 20 dB/km over a wavelength range of greater than 0.8-1.1µm, and, at the semiconductor laser wavelength of 0.9µm, has a value of 14dB/km. This is the first low-loss fibre to be made using glass.
