摘要：
In this paper, a novel Michelson fiber high-interference optical structure has been proposed. When an optical amplifier is applied into the interference optical path, the signal-to-noise ratio (SNR) of the signal light in the optical path is reduced by the amplifier generates amplifier spontaneous emission (ASE) noise. Through this new type of optical path, the ASE in the interference optical path can be suppressed, the SNR of the signal light can be improved, and a higher degree of interference can be achieved.
