摘要
摘要 利用计算机模拟研究了热传播过程，并确定了热电单光子探测器三层探测像素中的噪声，该探测器由吸收器（铂）、热电传感器（La0.99Ce0.01B6）和散热器（铂、钼）组成。研究了能量为 0.8-7.1 eV（1550-175 nm）的光子在不同厚度的吸收体中的吸收情况，这些吸收体具有很高的吸收效率。模拟基于有限体积的热传播方程。研究了出现在传感器上的信号的时间依赖性。确定了信号功率、噪声等效功率和信噪比。结果表明，带有铂吸收器的探测像素可以可靠地探测到能量为 3.1-7.1 eV 的单光子。
Platinum-Containing Detection Pixel of a Thermoelectric Single-Photon Detector
Using computer simulation, the processes of heat propagation were studied and noise was determined in a three-layer detection pixel of a thermoelectric single-photon detector, consisting of an absorber (Pt), a thermoelectric sensor (La0.99Ce0.01B6) and a heat sink (Pt, Mo). The absorption of photons with energies of 0.8–7.1 eV (1550–175 nm) in absorbers of various thicknesses, providing high absorption efficiency, was studied. The simulation was based on the heat propagation equations from a limited volume. The temporal dependencies of the signal appearing on the sensor were studied. Signal power, noise equivalent power, and signal-to-noise ratio were determined. It was shown that a detection pixel with a platinum absorber can reliably detect single photons with the energy of 3.1–7.1 eV.
