Abstract

We describe and model a non-cryogenic optical detector designed to count incident photons with metrological accuracy. Our design consists of a semiconductor device operating at -10 °C and is predicted to resolve pulses of up to 10 photons with an error rate of 2% in the input number of photons. We present an estimate of the overall device performance using a combination of estimates and simulations of optical loss, discrete electron loss and noise, and electronic noise.

摘要

我们描述并模拟了一种非低温光学探测器，其设计目的是对入射光子进行高精度计量计数。我们的设计包括一个在-10°C下工作的半导体器件，预计能分辨多达10个光子的脉冲，光子输入数量的错误率为2%。我们通过对光学损耗、离散电子损耗和噪声以及电子噪声的估计和模拟相结合的方式，对整个器件的性能进行了评估。
