环探测器光子计数

Photon counting with loop detector

Konrad Banaszek, Ian A. Walmsley

摘要:

我们提出了一种光子计数探测器的设计,能够解决多光子事件。该装置的基本元件是一个光纤环,它在快速电光开关的帮助下捕获输入场。单个弱耦合雪崩光电二极管用于检测从环路中提取的信号场的小部分。我们分析了环形探测器对任意输入场的响应,讨论了由计数统计重构未知场的光子数分布,以及探测器在条件态制备中的应用。

英文摘要:

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