A microscopic multimode theory of collinear type-I spontaneous parametric downconversion in a cavity is presented. Single-mode and multimode correlation functions have been derived using fully quantized atom and electromagnetic field variables. From a first principles calculation the FWHM of the single-mode correlation function and the cavity enhancement factor have been obtained in terms of mirror reflectivities and the first-order crystal dispersion coefficient. The values obtained are in good agreement with recent experimental results [Phys. Rev. A 62 , 033804 (2000)].

    ABSTRACT: A common way of increasing the efficiency of optical frequency conversion processes is by the injection of a coherent signal at the desired frequency. We study the efficiency of this method and its effect on the quantum statistics of the fields by performing theoretical analyses of the intracavity parametric chi((2)) processes of second harmonic generation and degenerate optical parametric oscillation with injected signal fields. We find that the threshold behaviour of the optical parametric oscillator with an injected signal field gives further insight into the normal threshold behaviour, considered as a limiting case as the signal field goes to zero. An injected signal is also shown to change the critical points of the systems, which define the region where the maximum of noise suppression and other quantum effects may be expected. We also investigate the self-pulsing behaviour of second harmonic generation, showing how an injected signal can affect the oscillations. We show the process of second harmonic generation can be blocked by an injected signal of the appropriate intensity, effectively removing the crystal from the cavity.

    ABSTRACT: A multimode theory describing the generation of photon pairs in a high-finesse Fabry-Perot cavity is presented. We also examine how interference of pairs produced with a local oscillator produces bunching and antibunching effects and also squeezing.

    ABSTRACT: In this paper we describe theoretically quantum control of temporal correlations of entangled photons produced by collinear type II spontaneous parametric down-conversion. We examine the effect of spectral phase modulation of the signal or idler photons arriving at a 50/50 beam splitter on the temporal shape of the entangled-photon wave packet . The coincidence count rate is calculated analytically for photon pairs in terms of the modulation depth applied to either the signal or idler beam with a spectral phase filter. It is found that the two-photon coincidence rate can be controlled by varying the modulation depth of the spectral filter.
