Abstract
We demonstrate a chirped microstructured polymer fiber Bragg grating based on taper technology for strain sensing application. The effective bandwidth of the grating is dependent on strain and remains practically constant irrespective of humidity changes. Besides wavelength shift measurement in temperature and humidity stable conditions with 9.02 pm/µε sensitivity, faster measurements under humidity fluctuations condition can be done by measuring the effective bandwidth of the grating.
