报告摘要：

   In this seminar an overview of research in optical fiber sensing at the Photonics Research Centre (PRC) at the Dublin Institute of Technology will firstly be described, followed by a detailed description of our research in fibre Bragg grating (FBG) and singlemode-multimode-singlemode (SMS) fibre structure.

   A typical optical SMS fibre structure is a combination of two different types of optical fibre, where a short length of multimode fibre is sandwiched between input and output singlemode fibres. SMS fibre structures are a promising approach for developing a variety of optical fibre components and sensors. Investigations are not only in designing new types of SMS structures but also in the combination of SMS structures and other optical fibre components such as Fiber Bragg Gratings and Long Period Gratings as a way of implementing all-fibre based components, for example refractive index sensors and filters for coarse wavelength division multiplexing communications systems. Potentially SMS structures will have new application areas in bio- and chemical sensing.
