"Edge filter temperature demodulation system based onarrayed wave-guide" by Hongqiang Li, Runjie Wang et al.
In order to overcome the large size and high price of the traditional arrayed wave-guide grating demodulation system, a demodulation scheme using a narrow-band light source as the input light source and adopting a combination of edge filter and arrayed wave-guide grating was proposed to realize the temperature demodulation experiment of fiber grating temperature sensor after packaging. Using the narrow-band light source as input, the edge filter method made the central wavelength shift of temper...
