摘要：

We designed and demonstrated a series of surface emitting quantum cascade lasers within the range of 4.5-9.0 mu m with different kinds of grating structure. The 2-order Bragg grating structure were exposed on top of the materials by means of optical lithography or holography and realized by deeper wet chemical etching. Many of these devices exhibit high performance in single-mode characteristics, operation temperature, and far field characteristics. These results give a cheerful prospect for the sensing and medical diagnosis application in the near future.
