详细描述了用光纤耦合、波长复用的全息光盘存储光路,指出在全息光盘驱动器即将市场化的今天,由于其光路简单、光学元件较少、性价比高,很有可能成为新的全息光盘驱动器的核心技术之一。由于短波长单模光纤及其双波长光纤分束器件的要求比较高,而用多模光纤进行准单模输出调整,以及用分光棱镜进行光束的分光,同时用对双波长敏感的光致聚合物材料进行存储,其光谱灵敏度均匀,光谱范围互不重叠。实验结果表明,光路结构合理,存储效果良好。
Holographic optical disc storage optical path using fiber coupling and wavelength multiplexing is described in detail. It is pointed out that holographic optical disc drive is becoming a new holographic optical disc drive due to its simple optical path, less optical components and high cost performance. One of the core technologies. Due to the relatively high requirements of short-wavelength single-mode optical fiber and its dual-wavelength optical fiber splitting device, multi-mode optical fiber is used for quasi-single-mode output adjustment and beam splitting by a dichroic prism, Materials for storage, the spectral sensitivity of the uniform, the spectral range of non-overlapping. The experimental results show that the optical path structure is reasonable and the storage effect is good.
