Exotic fibres
Optical fibres for telecommunications are well known, have been studied in detail, and are being applied extensively in public telephone networks. However there is rapidly increasing interest in the use of fibres as sensors and transducers. The paper describes the fabrication of optical fibres of novel design and incorporating new materials, including twisted, spun and helical-core fibres, as well as highly birefringent and single-polarisation, single-mode fibres. A new technique has been developed at Southampton University for incorporating rare-earth ions into the core of a single-mode fibre with the aim of producing laser action, as well as a distributed temperature sensor. These fibres have also provided, for the first time, continuous-wave operation when pumped by a simple semiconductor laser diode. The new fibre lasers have also been operated as amplifiers and tunable optical sources. They are simple, flexible, do not need optical alignment and are relatively unaffected by environmental conditions

Abstract
Optical fibres for telecommunications are well known, have been studied in detail, and are being applied extensively in public telephone networks. However there is rapidly increasing interest in the use of fibres as sensors and transducers. The paper describes the fabrication of optical fibres of novel design and incorporating new materials, including twisted, spun and helical-core fibres, as well as highly birefringent and single-polarisation, single-mode fibres. A new technique has been developed at Southampton University for incorporating rare-earth ions into the core of a single-mode fibre with the aim of producing laser action, as well as a distributed temperature sensor. These fibres have also provided, for the first time, continuous-wave operation when pumped by a simple semiconductor laser diode. The new fibre lasers have also been operated as amplifiers and tunable optical sources. They are simple, flexible, do not need optical alignment and are relatively unaffected by environmental conditions
