摘要：

We present the design of a novel metal micro-aperture surface emitting laser for tera byte optical data storage. The field distribution near micro-aperture is calculated by 2-dimensional finite element method, and it is shown that a spot size as narrow as 100 nm beyond a diffraction limit is obtainable.
