| Abstract |
We show that the reduction in photon-number fluctuations at laser threshold often cited as a fundamental laser property does not occur in small semiconductor lasers. The conventional theory of threshold noise is not valid in lasers with a spontaneous emission factor larger than 10-8. If the spontaneous-emission factor is larger than 10-4, the photon-number statistics even remain thermal far above threshold. We therefore conclude that the reduction in photon-number fluctuations is not a fundamental laser property but rather a matter of size and the corresponding relative importance of quantum fluctuations above threshold.
