Abstract

A team of engineers at Bilkent University, in Ankara, Türkiye, has built a nanoscale optical element not on top of a silicon wafer, but rather in a layer below the surface. To achieve this, they used a special type of laser known as a Bessel beam, whose light can pass through the surface of a wafer and interact with the silicon below. Because the Bessel beam's light doesn't diffract, it's now possible to create two-dimensional structures inside the silicon as small as 100 nanometers.

激光在硅中嵌入纳米级器件

位于土耳其安卡拉的比尔肯特大学（Bilkent University）的一个工程师小组不是在硅晶片的顶部，而是在其表面下的一层制造出了一个纳米级光学元件。为了实现这一目标，他们使用了一种被称为贝塞尔光束的特殊激光，其光线可以穿过硅片表面并与下面的硅相互作用。由于贝塞尔光束的光线不会发生衍射，因此现在可以在硅片内部创建小至 100 纳米的二维结构。
