|Title:||Thermal response of Bragg gratings in PMMA microstructured optical fibers||Authors:||Carroll, Karen E.

|Issue Date:||2007||Publisher:||Optical Society of America||Source:||Optics Express, Volume 15, Issue 14, pp. 8844-8850||Abstract:||We report on the thermal characteristics of Bragg gratings fabricated in polymer optical fibers. We have observed a permanent shift in the grating wavelength at room temperature which occurs when the grating has been heated above a threshold temperature. This threshold temperature is dependent on the thermal history of the grating, and we attribute the effect to a shrinking of the fiber. This effect can be avoided by annealing the fiber before grating inscription, resulting in a linear response with temperature and an increased linear operating temperature range of the grating.||URI:||http://ktisis.cut.ac.cy/handle/10488/1148||DOI:||10.1364/OE.15.008844||Rights:||© 2007 Optical Society of America|
