#### Abstract

Using receiver eigenmodes, we perform a time-dependent analysis of optical receivers whose optical inputs are corrupted by the amplified spontaneous emission. We use Gaussian receivers for the analysis with Gaussian input pulses. We find the number of contributing eigenmodes increases as the measurement time moves from the pulse center towards the pulse edges at the output of the optical receiver's electrical filter. This behavior is dependent on the bandwidth ratio between the optical and the electrical filters as well as the input pulse's time width.
