We propose and test experimentally a new scheme to implement spatially multiplexed multiwavelength holographic memory. An electro-optically modulated phase grating array on LiNbO(3) substrate is used as a guided-wave interconnect to activate the reconfigurable reference beam. The object beam is provided by free-space interconnect. An electro-optic modulation efficiency of 18 +/- 2.5% is achieved with an applied voltage of 100 V. The reference beams with different diffraction angles can implement the angle-multiplexing holographic recording. We believe this is the first report of the implementation of guided-wave electro-optic interconnect together with free-space interconnect in holographic memory applications.
我们提出并通过实验测试了一种实现空间复用多波长全息存储器的新方案。基于铌酸锂(LiNbO₃)衬底的电光调制相位光栅阵列用作导波互连,以激活可重构参考光束。物光束由自由空间互连提供。在施加100V电压时实现了18±2.5%的电光调制效率。具有不同衍射角的参考光束可实现角度复用全息记录。我们认为这是关于在全息存储应用中实现导波电光互连与自由空间互连相结合的首次报道。
