中文摘要	an enhanced technique for interrogating fiber bragg grating wavelength shift using cascade wavelength division multiplexer (wdm) couplers was proposed and demonstrated. three wdm couplers which show a linear filter function over the expected wavelength range are employed and cascaded to track bragg wavelength shifts. compared with single wdm demodulator. sharper spectral slope is obtained and considerable linear filter range is kept. the static and dynamic strain sensor demodulation experiments demonstrated that the simple passive technique improves the sensitivity approximately two times and keeps 5nm linear demodulation range based on our devices. the cascade wdm coupler demodulation system has high scan rate which can be used to monitor fast vibration.
