Paper Abstract

The response of a transmission spectrum to applied axial strain for an in-fiber Mach-Zehnder interferometer that based on two tcascaded long-period fiber gratings is studied theoretically and experimentally. Linear strain-induced wavelength shift with a tuning rate of -0.6 pm per microstrain has been achieved, which suggests that such an optical fiber device can be used as a cost effective, tunable wavelength-division multiplexing (WDM) filter.
