摘要：
Semiconductor cascade lasers have larger photon noise than conventional semiconductor lasers as a result of positive correlations in photon emission in different gain stages which are connected electrically in series. The photon noise of a cascade laser can be related to the photon noise of a single-stage laser with a scaled external circuit impedance. This scaling relation for the photon noise holds for bipolar as well as unipolar cascade lasers.
