The evaluation of temporally resolved photon statistics [1] plays a crucial role in a wide variety of quantum optical applications. Examples range from the discrimination of coherent states in quantum receivers [2] to the characterization of entangled states and single photon sources [3]. An important figure characterizing the quality of a single photon source is the the effective number of modes. We evaluate the single photon statistics in light generated by PDC inside a whispering gallery mode resonator and measured with a transition edge sensor [4] with respect to the effective mode number. In doing so, we compare two different approaches analyzing either the second-order intensity correlation function or a maximum likelihood estimation based on multimode photon statistics.
