摘要：
Based on the statistical properties of amplified spontaneous emission, the photodetection noise spectrum at the output of an optical amplifier is calculated. The results revealed that the signal-spontaneous emission beat noise spectrum is a transposition of the spontaneous-emission spectrum to the low-frequency domain, and the spontaneous emission-spontaneous emission beat noise spectrum is the auto-correlation function of the spontaneous-emission spectrum. These theoretical results are verified experimentally on an erbium-doped fiber amplifier, filtered by a Mach-Zehnder interferometer.
