| Abstract(in English) | A fiber Bragg grating (FBG) is an attractive optical filter device because of its narrow wavelength selectivity, low loss, compactness, and low cost. Therefore, it is useful for applications such as coherent optical communication systems, optical sensing and optical metrological standard. These applications require both a narrow bandwidth and a high side lobe suppression ratio. We have already demonstrated a 1.3GHz ultranarrow FBG filter with a side lobe suppression ratio of 13dB. In this paper, we report a 0.4GHz FBG filter with a side lobe suppression ratio as high as 30dB by combining a uniform FBG and a λ/4 shifted FBG. |
