摘要

研制了一种响应5ns脉冲、开关能量为4.9 nJ的非易失性磁光开关。该开关的工作原理是使用脉冲电流感应磁场磁化薄膜磁铁,薄膜磁铁反过来产生静态磁场,使磁光移相器磁化。由于相移不需要持续的功率应用,开关在不频繁的开关期间实现低功耗。此外,由于操作依赖于磁化逆转(一种非破坏性效应),因此证明了1.8万亿次循环的高写循环耐久性。

Trillion-switching-cycle endurance and high-speed operation of a nonvolatile magneto-optic switch.

A nonvolatile magneto-optic switch responding to a 5 ns pulse with a switching energy of 4.9 nJ was demonstrated. The switch operates by using a pulsed current-induced magnetic field to magnetize a thin-film magnet, which in turn generates a static magnetic field that magnetizes the magneto-optic phase shifter. Because the phase shift is maintained without continuous power application, the switch achieves low power consumption during periods of infrequent switching. Furthermore, since the operation relies on magnetization reversal-a nondestructive effect-a high write-cycle durability of 1.8 trillion cycles was demonstrated.
