摘要

摘要我们报告了一种使用频率相关光子对光纤源的线性吸收光谱实验。被研究物体由频率纠缠光子对的信号光束照射。由于纠缠光子的紧密相关性，可以通过惰光束测量物体的吸收光谱，同时计算两个通道的重合度。分析了鬼影光学的主要优势，包括由于只检测成对重合光子和切断所有单个背景光子而显著降低噪音，以及研究样品的潜在灵敏度，这在处理生物物体时尤为重要。

Four-Photon Mixing in Ghost Fiber Spectroscopy

Abstract

We report an experimental implementation of linear absorption spectroscopy using a fiber source of frequency-correlated photon pairs. The object under study is illuminated by a signal beam of a photon pair entangled in frequency. Due to the tight correlation of entangled photons, the absorption spectrum of the object can be measured from the idler beam, counting coincidences in both channels. The main advantages of ghost optics are analyzed, including significant noise reduction due to detecting only paired coincidences and cutting off all single background photons, as well as the potential sensitivity of studying samples, which is especially important when working with biological objects.
