| Abstract: | To obtain the weak signal light from the high background light, a narrow bandwidth Faraday anomalous dispersion optical filter (FADOF) was studied. The theoretical model for the filter was reported. The Faraday anomalous dispersion optical filters have two working modes: two side peak transmission and center peak transmission. The former work mode can get single peak transmission of 25% with a bandwidth of about 600 MHz. The other work mode can get a spectra with a transmission rate of almost 100% and a bandwith of about 700 MHz. The experimental measurements are consistent with theoretical results. |
