摘要

本文直接证明了在bi2sr2cacu $ {2} \mathrm{0} {{8+} {\delta}}$单晶上形成的两个本征Josephson结叠加中激发的同步宏观Josephson振荡。通过对单独偏置台地和同时偏置台地发射的太赫兹波的偏振分析，发现了两个台地中约瑟夫森振荡通过基晶体之间的强耦合。

Mutual Synchronization of Terahertz Emissions from Multiple Intrinsic Josephson Junction Mesas

We present a direct proof of synchronized macroscopic Josephson oscillations excited in two intrinsic Josephson junction stacks formed on a Bi 2 Sr 2 CaCu $_{2} \mathrm{O}_{{8+} {\delta }}$ single crystal. The strong coupling between the Josephson oscillations in the two mesas via the base crystal is detected by polarization analysis of emitted terahertz waves from individually biased mesas and simultaneously biased mesas.
