摘要：

Optically preamplified receivers can achieve sensitivities close to those possible with heterodyne detection, although this generally requires the bandwidth of the amplified spontaneous emission (ASE) to be limited through the addition of an optical filter after the amplifier. This paper examines the noise sources in preamplified receivers, and considers the particular case where a Fabry-Perot etalon is used as the filter.
