Abstract

Demodulation system for applied to seismic detection, erbium-doped fiber super fluorescent source combined with demodulation, the design of optical fiber Bragg seismic detection demodulation system based on ASE source, optical power output of 6.9 mW (8.43 dBm), spectral up along the width of 3 nm and down along the width of 2.5 nm range linear fitting are 0.9994 and 0.9995 respectively. The output spectrum of SFS has good linearity in the monotone interval, ensure the detection signal enough tuning range and good sensitivity , it was make the SFS can be reliably used for fiber Bragg grating seismic detector as edge filter demodulation method.
