卡西米尔力起源于真空零点能，是最有趣的纯量子效应之一。随着片上器件尺寸的迅速减小，纳米材料的研究引起了人们的广泛关注。在这里，我们研究了光机械诱导透明（OMIT）与可调卡西米尔力。我们发现，光输出速率可以显着改变真空力，甚至终止，然后恢复，表明一个高度可控的光开关。我们的研究结果解决了利用真空的力量设计奇异的光学纳米器件的可能性。
The Casimir force, originating from vacuum zero-point energy, is one of the most intriguing purely quantum effects. It has attracted renewed interests in current field of nanomechanics, due to the rapid size decrease of on-chip devices. Here we study the optomechanically-induced transparency (OMIT) with a tunable Casimir force. We find that the optical output rate can be significantly altered by the vacuum force, even terminated and then restored, indicating a highly-controlled optical switch. Our result addresses the possibility of designing exotic optical nano-devices by harnessing the power of vacuum.
