我们证明了亚毫秒开关时间的全光液晶（LC）开关的可行性。这种开关是通过使用“光镊”对三维捕获的微观微滴进行光学操纵来实现的。“偏振器/LC液滴/分析仪系统的传输可以在高达10（3）Hz的频率下进行调制，比迄今为止证明的向列型LC的响应速度更快。响应对应于LC液滴旋转π/4角度时的亚毫秒切换时间。还证明了LC液滴与入射平面偏振光束的平面的对准。(c)1999年美国物理学会。【S0003-6951（99）00124-2】。
We demonstrate the feasibility of an all-optical liquid-crystal (LC) switch with submillisecond switching time. This switch is realized by optical manipulation of a three-dimensionally trapped microscopic nematic LC droplet using an "optical tweezers." Transmission of a polarizer/LC droplet/analyzer system can be modulated at frequencies as high as 10(3) Hz, a faster response than that of a nematic LC demonstrated so far. The response corresponds to a submillisecond switching time when the LC droplet is rotated by an angle of pi/4. The alignment of the LC droplet to the plane of the incident plane-polarized beam is also demonstrated. (c) 1999 American Institute of Physics. [S0003-6951(99)00124-2].
