  • Abstract
    We present an analysis and explanation of the presence of backreflected signal in an all-fiber bandpass transmission filter. The device is based on a 3-dB fused coupler and two Bragg gratings photoimprinted in the output arms of the coupler. Solutions to correct this problem are proposed.
