  • Abstract
    Reports the first detailed investigation of the effect of semiconductor laser amplifier noise figure on the sensitivity of a heterodyne receiver. Independent measurement of the amplifier spontaneous noise spectral density confirms that local oscillator-spontaneous emission beat noise accounts for all of the observed penalty.
