Carbon fiber based composite material is of considerable interest for the replacement of steel in large concrete structures, such as bridges, where corrosion is a serious problem. A new two-span concrete highway bridge built in the city of Calgary in

A number of major challenges face the practical implementation of Smart Structure technology. One of the most important is concerned with the communication link between the structure's resident fiber optic sensing system and the support structure. In

In this paper, we propose a versatile and compact mechanism for tunable grating dispersion. A segmented piezoelectric stack with individually controlled segments was used to control the local strain at 21 positions along the grating. By step-wise mon

Independent tuning of cascaded long period fibre gratings (LPFGs) is demonstrated. This involves applying a small controllable bend to each LPFBG, resulting in a synthetic spectral response due to the spectral overlap. This technique provides high sp

A novel tunable fibre bandpass filter based on a linearly chirped fibre Bragg grating (LCFBG) has been demonstrated. The transmission peaks in the LCFBG stopband are electronically induced by controlling the strain distribution along the LCFBG using
