我们提出了一种用于近场光学探测的微孔径垂直腔面发射激光器（VCSEL）。我们提出了第一个演示的二维成像使用的电压变化信号从一个微孔VCSEL，这是由与物体的相互作用引起的。图像的空间分辨率低于200 nm，这是波长的五分之一。
We propose the use of a microaperture vertical cavity surface emitting laser (VCSEL) for near-field optical probing. We present the first demonstration of two-dimensional imaging using the voltage change signal from a microaperture VCSEL, which is induced by interaction with an object. The spatial resolution of the image is below 200 nm, which is one fifth of the wavelength.
