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|
