Abstract

The strain and temperature responses of transmission dips at 2/3 of the Bragg wavelength in type I and IIA fiber Bragg gratings are presented. The existence of such dips is related to complex features that have been observed in microscope images of fiber Bragg gratings. The temperature and strain responses are as expected and demonstrate the suitability of using signals from both the Bragg wavelength and 2/3 of the Bragg wavelength for the simlutaneous and co-located measurement of strain and temperature, using a single light source.
