Characterisation of Multicore Tellurite Optical Fibre

Tellurite glass fibre has great potential for use in near and mid infrared (mid-IR) optics. The high nonlinearity and its excellent transmission properties in the infrared make it an ideal candidate for many linear and nonlinear optical devices (Abedin, 2006). These can be devices for chemical sensing, nonlinear optical signal processing, Raman amplification or mid-IR continuum generation. Tellurite glasses are also an excellent host for rare earth ions with their low phonon energy. In this paper we report on the fabrication and characterisation of a multiple core tellurite glass fibre. Multiple core fibres can offer new device designs such as arrayed fibre lasers and amplifiers, chemical sensors and bend sensors (Flockhart et al., 2003).
