Absence of Long-Range Coherence in the Parametric Emission from Photonic Wires
arXiv:cond-mat/0512464 · doi:10.1103/PhysRevB.74.245316
Abstract
We analytically investigate the spatial coherence properties of the signal emission from one-dimensional optical parametric oscillators. Because of the reduced dimensionality, quantum fluctuations are able to destroy the long-range phase coherence even far above threshold. The spatial decay of coherence is exponential and, for realistic parameters of semiconductor photonic wires in the strong exciton-photon coupling regime, it is predicted to occur on an experimentally accessible length scale.
