摘要/Abstract

摘要： 光纤的典型功能是通信和传感，该文赋予光纤存储的功能，设计了一种全光纤存储器，以满足光纤通信系统智能化发展的需要。利用单模光纤（single-mode fiber,SMF）与多模光纤（multimode fiber,MMF）同轴焊接，并通过磁控溅射方法将Ge₂Sb₂Te₅（GST）材料沉积在MMF端面，端面出射的类贝塞尔光束可以切换GST的相态。MMF的长度影响端面光场，最终选择1.5 mm长的MMF以实现具有任意级别访问能力、高光学对比度、稳定重复性良好的非易失性存储器。该存储器可以实现11级存储，并能够在11个存储等级间进行任意且稳定的切换，光学对比度达到50%，重复循环至少34次。

Abstract: The typical functions of optical fiber are communication and sensing, this paper gives the function of optical fiber storage and designs an all-fiber memory to meet the needs of intelligent development of optical fiber communication systems. In this paper, single-mode fiber (SMF) and multimode fiber (MMF) are used to coaxial soldering, and Ge₂Sb₂Te₅ (GST) material is deposited on the end face of MMF by the magnetron sputtering method, then the end face will emit the Bessel-like beam that can switch the phase state of GST, the length of MMF affects the end face light field, and finally 1.5 mm long MMF is selected to achieve non-volatile memory with arbitrary level access ability, high optical contrast, good stability, and high repeatability. The memory can realize 11 levels of storage randomly and stably, with an optical contrast of 50% and repeated cycles at least 34 times.

Key words: optical memory, optical fibers, phase change material, Bessel-like beams
