波导光存储信息读出方法实验研究

Experimental study of the information readout method in a multlayered waveguide memory

波导多层光存储器件是由多层平面光波导结构叠加而成,一层光波导结构记录一层信息。基于波导原理,信息逐层读出时可以有效地防止层间串扰从而实现多层信息连续读出,因而单层信息的读出是波导多层光存储的关键技术之一。本文对波导单层信息读出方法进行实验研究,实现了单层信息的静态读出,对该技术的进一步研究及实用化有重要的参考价值。

In a multlayered waveguide memory, store device is stacked up of many plane waveguide units with information one by one. Base on waveguide theory this device can prevent crosstalk so that all information can be read out continuously. So information readout technology for single layer is very important. In this paper, experimental study of information readout method is done to realize information readout statically.
