F-state based p ermanent optical data storage in bacteriorho dopsin film

摘要: 在线偏振飞秒激光激发下，菌紫质通过双光子光化学反应可以生成具有永久光致各向异性的蓝移产物F540态。基于F540态的永久光致各向异性，通过调控飞秒激光空间光场分布，可以在菌紫质薄膜中实现永久光信息存储。本文使用纯相位型空间光调制器调制飞秒激光光场，在物镜焦平面上生成光学点阵图案，可以将信息快速记录在菌紫质薄膜中。同时，通过改变入射激光偏振方向，可以实现偏振复用光存储，这在高密度光存储和数据加密领域具有潜在应用。

Abstract: Upon excitation of high intensity linearly polarized femtosecond laser, a blue-shifted two-photon induced photo-product named F540 state with permanent photo-induced anisotropy is observed in bacteriorhodopsin (BR) films. Based on the F-state, permanent optical data storage can be realized with spatial field modulation of femtosecond laser. By using a phase-only spatial light modulator to modulate the spatial phase distribution of the incident femtosecond laser beam, we generate spot-patterns in the focal plane of the microscopic objective lens, and the patterns are recorded in the BR film. At the same time, by varying the polarization direction of the excitation laser beam, polarization-multiplexed optical data storage in the BR film is demonstrated, which is applicable to high-density optical data storage and optical information encryption.
