报告内容：In this seminar an overview of research inphotonics by Dr. Qiang Wu will firstly be described, followed by a detaileddescription of his research in fibre optic interferometer and sensingapplication.A typical fibre interferometer is a singlemode –multimode – singlemode (SMS) fibre structure, which is a combination of two different types ofoptical fibre, where a short length of multimode fibre is sandwiched betweeninput and output singlemode fibres. SMS fibre structures are a promisingapproach for developing a variety of optical fibre components and sensors.Investigations are not only in designing new types of SMS structures but alsoin the combination of SMS structures and other optical fibre components such asFibre Bragg Gratings and Long Period Gratings as a way of implementing all-fibrebased components, for example refractive index sensors and filters for coarsewavelength division multiplexing communications systems. Tapered SMS structureshave proved to be able to improve sensitivity significantly and have beenapplied in new applications including bio- and chemical sensing.
