摘要:

我们提出了一个建议的设计,一对破坏的远红外和亚毫米波辐射的光电探测器。在超导吸收体中,超导耦合辐射产生准粒子,准粒子的密度用单个库珀对盒测量。使用电磁振荡器或微波谐振器进行读出,这非常适合于大型阵列中的频率复用。探测器灵敏度的理论极限进行了讨论和建模,预测的灵敏度媲美过渡边缘传感器和微波动力学电感探测器。我们预计,该探测器可用于解决远红外和亚毫米天文学的关键科学目标。

英文摘要:

We present a proposed design for a pair-breaking photodetector for far-infrared and sub-millimeter radiation. Antenna-coupled radiation generates quasiparticles in a superconducting absorber, the density of which are measured using a single Cooper-pair box. Readout is performed using an electromagnetic oscillator or a microwave resonator, which is well suited for frequency multiplexing in large arrays. Theoretical limits to detector sensitivity are discussed and modeled, with predicted sensitivities rivaling transition-edge sensors and microwave kinetic inductance detectors. We anticipate that this detector can be used to address key scientific goals in far-infrared and sub-millimeter astronomy.
