    "abstract": "We propose a design for a photon counting detector capable of resolving\nmultiphoton events. The basic element of the setup is a fiber loop, which traps\nthe input field with the help of a fast electrooptic switch. A single weakly\ncoupled avalanche photodiode is used to detect small portions of the signal\nfield extracted from the loop. We analyze the response of the loop detector to\nan arbitrary input field, and discuss both the reconstruction of the photon\nnumber distribution of an unknown field from the count statistics measured in\nthe setup, and the application of the detector in conditional state\npreparation.",
