|Title:||Observation of axial acoustic waves in multimode PMMA optical fibres and implications for a new class of optical fibre sensor||Contributor(s):||Ernest, Allan (author); Lamb, David (author)||Publication Date:||2005||DOI:||10.1088/1742-6596/15/1/045||Handle Link:||https://hdl.handle.net/1959.11/3173||Abstract:||Observations of axial acoustic waves in multimode polymethylmethacrylate (PMMA) optical fibres are reported. Rapid electrostriction was induced in a 1.25m length of PMMA optical fibre using a pulsed transverse electric field of ~10⁶ V m⁻¹. By observing the effects of birefringence on a polarised laser beam, acoustic waves travelling with a speed of 1050m s⁻¹ were observed to travel between the fibre ends. Simple calculations indicate that these acoustic waves comprised shear waves, although propagation of surface waves could not be ruled out. The implications of these observations in terms of a new class of optical fibre sensors based on the propagation of axial acoustic waves are also discussed.||Publication Type:||Journal Article||Source of Publication:||Journal of Physics: Conference Series, 15(1), p. 270-275||Publisher:||Institute of Physics and IOP Publishing Limited||Place of Publication:||Bristol, UK||ISSN:||1742-6596||Field of Research (FOR):||020501 Classical and Physical Optics||Socio-Economic Outcome Codes:||861503 Scientific Instruments||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 231
