创造和利用亚波长尺寸的强光源开辟了光学新领域——近场光学。近场光学最有吸引力的应用之一是近场光学数据存储。高度需要具有高密度和高数据传输速率的光学存储器，以利用高吞吐量纳米级光源阵列在介质上写入和读取位。在本文中，我们提出了一种用于光学近场存储头的垂直腔表面发射激光器（VCSEL）和孔径阵列的混合结构，即VCSEL/NSOM。提出了一种利用硅微加工技术制造孔径阵列的技术方案。对硅微机械孔径阵列孔径处近场光的光学性能进行了研究。演示了使用所制造的结构在相变（PC）介质上写入和读取位的主要结果。
To create and utilize a strong light source with sub-wavelength size has opened up a new frontier in optics, the near-field optics. One of the most attractive applications of the near-field optics is near-field optical data storage. The optical memory with high density and high data transfer rate is highly demanded to utilize an array of high throughput nano-scaled light sources for writing and reading bits on a medium. In this paper, we propose a hybrid structure of vertical cavity surface emitting laser (VCSEL) and aperture array for optical near-field memory head, namely VCSEL/NSOM. A technological solution for fabrication of the aperture array with Si micromachining technology is presented. An investigation of the optical performance of the near-field light at the apertures of the Si micromachined aperture array is presented. The primary result of writing and reading bits on a phase change (PC) medium using the fabricated structure is demonstrated.
