Topic：Research and Technologies at Aston  University – Advanced fibre grating devices and  applications

Time： 2015年9月7日（周一）上午10:00-11:30

Venue： 教5-326学术厅

Speaker： Prof Lin Zhang (Ph.D), the Head of the  Department of Electrical, Electronic and Power Engineering and the Deputy  Director of AiPT at Aston University.

Aston Institute of Photonic  Technologies (AiPT) is  the one of largest research centres in the UK. With more  than 70 active researchers, it has an impressive portfolio of grant funding,  industrial and international collaborations, spin-out companies, highly cited  research papers and patents, all demonstrating excellence in the field of  photonics. AiPT has a world-recognised record of achievement in high-speed  optical communications, fibre-optic devices and nonlinear photonic technologies.  The research profile of AiPT includes theoretical, numerical and experimental  studies on optical communications, fibre lasers, fibre sensing technologies,  bio-photonics and laser material processing and fibre grating fabrication. AiPT  is well funded from a range funding bodies including EPSRC, UK Innovate, EU,  Royal Society, Leverhulme Trust and industry. AiPT has a strong record of  successful international collaboration. During the past five years, AiPT has  co-authored publications with colleagues from more than 70 UK and overseas institutions and  companies, and has hosted more than 150research visitors for work periods  ranging from one week to one year.

Prof Lin Zhang (Ph.D) is the Head of the Department of Electrical, Electronic and Power  Engineering and the Deputy Director of AiPT at Aston University. Her research  interests are primarily in the field of optical fibre grating devices and the  applications in optical communications, signal processing, bio-photonics, and  fibre laser and smart sensing technology. Her research output so far includes  ~400 research papers published in peer-review journals and international  conferences.

The  talk will give an overview of the research activities of the AiPT with the  emphasis on fabrication techniques and sensing applications of advanced optical  fibre grating devices created in normal and special optical fibres by UV- and  femtosecond-laser inscription. A range of novel optical fibre grating devices  and systems based on Bragg, long-period and tilted structures fabricated in  D-shape, multi-mode and multi-core fibres will be discussed. The most recent  developments in tilted grating based novel polarisation devices and their  function in fibre laser systems will be reviewed.
