半约瑟夫森激光器中电压起伏的光学稳定

Optical stabilization of voltage fluctuations in half-Josephson lasers

F. Godschalk, Yu. V. Nazarov

摘要:

最近提出的一种被称为半约瑟夫森激光器的装置,在装置的引线之间的光学相位和超导相位差之间提供锁相。在本文中,我们建议利用这种相位锁定稳定的电压波动,通过两个光学反馈方案。第一个方案涉及一个单一的半约瑟夫森激光器,并允许显着降低超导相位差的扩散系数。第二种方案涉及一个稳定的光源和波动的半约瑟夫森激光器,并允许淬火的激光器的相对相位的扩散。这开辟了超导相位和电压波动的光学控制的前景。

英文摘要:

A recently proposed device, dubbed half-Josephson laser, provides a phase-lock between the optical phase and the superconducting phase difference between the leads of the device. In this paper we propose to utilize this phase-lock for stabilization of voltage fluctuations, by two optical feedback schemes. The first scheme involves a single half-Josephson laser and allows to significantly decrease the diffusion coefficient of the superconducting phase difference. The second scheme involves a stable optical source and a fluctuating half-Josephson laser and permits quenching of the diffusion of the relative phase of the lasers. This opens up perspectives of the optical control of the superconducting phase and voltage fluctuations.
