介绍了均光波导多层存储器的基本结构和原理。波导多层存储器通过收集波导侧面信息符发出的散射光来读取数据,而均光波导多层存储器的设计主要是为了解决波导多层存储器侧面散射光强不均匀的问题。有一种方法就是通过改变信息符深度来实现均光。理论推导表明信息层表面的信息符深度沿着传导光传播方向逐渐增加时可以实现波导侧面散射光强的均匀分布,而且波导各个不同位置处信息符的深度值也可以通过拟合和计算得到。为了证明理论的正确性,设计了原理性实验,完成了原理性实验器件的研制。实验对均光波导多层存储器的结构、原理以及均光方法的可行性进行了验证。实验还将均光波导多层存储器的性能与一般的波导多层存储器作了对比,实验效果良好。
The basic structure and principle of multi-level memory with uniform optical waveguide are introduced. Waveguide multilayer memories read the data by collecting the scattered light from the side information of the waveguides. The design of the multilayer waveguide with uniform waveguides is mainly to solve the problem of nonuniform scattering of light intensity on the side of the waveguide multilayer memory. One way to achieve this is by changing the depth of the message. The theoretical deduction shows that the depth of information symbol on the surface of information layer increases along the direction of propagation of light, and the light intensity distribution on the side of waveguide can be uniformly distributed. The depth values of information symbols at different positions of the waveguide can also be fitted and calculated. In order to prove the correctness of the theory, we designed the principle experiment and completed the development of the principle experiment device. The experiment verifies the structure, principle and the feasibility of the homogenization method of the multilayer optical waveguide. The experiment also compares the performance of the multilayer optical waveguides with that of the multilayer multilayer waveguides, and the experimental results are good.
