摘要 | The light waveguide consists of an optically transparent body (1) at one end cut to a sharp tip (2) and polished optically flat at the other (3). A metallization (6) on its surface is thick enough to be opaque. By pressing the waveguide against a rigid plate (16), the metallization (6) is plastically deformed so as to expose a tiny aperture (28) at the tip (2) of the body through which light can pass. By carefully controlling the deformation of the metallization (6), the diameter of the aperture (28) can be kept between 10 and 500 nm. …The application of the aperture (28) when incorporated in the semiconductor laser of the read/write head of an optical storage device is described. |
其他摘要 | 光波导包括光学透明体(1),其一端切割成尖锐的尖端(2)并且光学平坦地抛光到另一端(3)。其表面上的金属化(6)足够厚以致不透明。通过将波导压在刚性板(16)上,金属化(6)塑性变形,从而在光体可以通过的主体的尖端(2)处暴露出微小的孔(28)。通过仔细控制金属化(6)的变形,孔(28)的直径可以保持在10和500nm之间。当描述光学存储装置的读/写头的半导体激光器中时,应用光圈(28)。 |
