Paper Abstract

The technology of single-mode optical soft glass fibres is developed. The well-known rod in tube technique with multiple sleeving was taken to achieve proper dimensions. The ultrasonic mill-drill was used to prepare different structures: high ▵ , high birefringent, D-shaped, multicore, metal wire/glass compound and doped. The temperature processes were carried out very carefully to avoid glass decomposition. The geometry, refractive index profiles, mode near field patterns and λc agreed with the predicted and material data. The losses were reasonably low, better then 370 dB/km (800 nm). The enhanced Verdet constants and nonlinear coefficients values, high dopants levels and other special properties including low process temperatures are very attractive for fibre short range applications, sensors and devices e.g. polarizers, couplers, lasers, filters.
