Enhanced polarisation maintaining fibres for specialised applications
Corning Inc., USA, has recently introduced two new polarisation maintaining (PM) optical fibres with higher numerical aperture (NA) and high-temperature polyimide coating. These newest additions to Corning’s broad specialty fibre portfolio capture emerging technology trends in aerospace, fibre optic gyroscope, and sensor markets for improved laser coupling efficiency, as well as deployment in harsh environments.
Corning’s high NA fibres are optimised with 30% higher NA versus standard fibres and are available in PM.1300 with 125µm cladding, and PM.850 with 80µm reduced cladding for miniaturised devices. These highly bi-refringent fibres are designed with excellent dimensional uniformity and low beat lengths for applications including planar waveguides, visible light sensor probes, and Faraday effect devices. In addition, Corning has introduced polarisation maintaining fibre with polyimide coating designed for high-temperature and high-pressure applications, such as aerospace platforms, radiation analysis, and down-hole geological sensing. Available initially at 1,300nm wavelength, Corning’s polyimide speciality fibre consists of a 10µm coating applied over standard 125µm cladding to provide a fatigue resistant PM fibre for use in extreme temperature environments. Along with these new products, Corning has also announced enhanced specifications for all polarisation maintaining products, including shorter beat length range, improved crosstalk, and enhanced fibre geometry.
