Abstract :
Cladded-type fluoride glass fibres with a transmission loss of 0.1 dB/m at 2.5 ¿m and 0.3 dB/m at 3.6 ¿m, respectively, were fabricated by a novel casting method. Relative refractive-index differences between core and cladding ranging from 0.17% to 0.33% were obtained using BaF2-GdF3-ZrF4-AlF3 glasses as core and cladding components.
