The grating has been UV-written with the phasemask technique using a 325 nm HeCd laser. The static tensile strain sensitivity has been measured as 0.64 pm/μstrain, and the temperature sensitivity was -60 pm/°C. This is the first 870nm FBG and the first demonstration of a negative temperature response for the TOPAS FBG, for which earlier results have indicated a positive temperature response. The relatively low material loss of the fiber at this wavelength compared to that at longer wavelengths will considerably enhance the potential utility of the TOPAS FBG. | ISBN: | 978-081948246-4 | ISSN: | 0277-786X | DOI: | 10.1117/12.884986 | Rights: | © 2011 Society of Photo-Optical Instrumentation Engineers (SPIE). | Type: | Conference Papers | Affiliation: | Technical University of Denmark Cyprus University of Technology Aston University |
