Software for complete mode structure analysis of a light field
Ivan A. Burenkov, Sergey V. Polyakov
We present a software package aimed at simulating photon-number probability distributions of a range of naturally occurring classical and non-classical states of light. This software can generate arbitrary probability distributions based on the known mode structure of a light field. It also can solve the reverse problem, i.e. reconstructing the mode structure of a light field based on a given probability distribution. The mode structure fully describes a light field and contains the information about the source of light without a direct access to the source. The multimode fields simulated by this software include those comprised of a number of thermal modes and an optional Poisson mode. In addition, conjugated multimode sources (such as those created via parametric downconversion (PDC) or four-wave mixing (FWM)) can be simulated. Using this software, and with a minimal set of assumptions, we demonstrate a nearly- perfect reconstruction of multimode fields comprised of several correlated modes corresponding to squeezed vacuum states and several uncorrelated thermal and Poisson modes corresponding to background light.
