Abstract
A general, systematic approach to the analysis of multimode squeezed light produced by parametric downconversion is presented. This approach involves finding the eigenvectors of a matrix which is directly related to the parametric gain. It is found that typical setups for squeezed light measurement do not optimally probe the squeezed field and that shaping the local oscillator in accordance with the predictions of the theory could increase the measured amount of squeezing in such experiments by at least several dB.
