摘要: A single long-period fibre grating was written in a biconical taper made from standard communications step-index optical fibre, resulting an interferometric sensor device that provided resolution of 1 × 10-4 for refractive indices the range 1.30 to 1.34, suggesting these devices may be suitable use with aqueous solutions. © IEE 2005.
