Abstract :
Loss minima in two fluoride glass and chalcogenide glass fibres were calculated. The intrinsic losses are predicted to be 1 × 10¿3 dB/km at 3.4 ¿m for BaF2-GdF3-ZrF4 glass fibre, 1 × 10¿2 dB/km at 2.7 ¿m for BaF2-CaF2-YF3-AlF3 glass fibre and 1 × 10¿2 dB/km at 4.5 ¿m for GeS3 glass fibre.
